Trivia: Born July 29th, 1974, genial actor Josh Radnor established himself as a television star almost exclusively with one single, charming role: that of Ted Mosby, the young man whose future self (the voice of Bob Saget) narrates the story of how he snagged his wife and the mother of his children, on the sitcom How I Met Your Mother. That program earned stellar notices when it premiered in 2005, suggesting a lengthy run and newfound stardom for the young actor. Radnor's resumé also includes guest appearances on such programs as ER, Six Feet Under, and Law & Order.

Trivia: Born January 18th, 1980, the first decade or so of Jason Segel's career as a Hollywood actor, he spent his time earning cult-favorite status -- beginning with the jet-black comedy Dead Man on Campus (1998), then the NBC comedy drama Freaks and Geeks (1999). Segel subsuquently achieved broader recognition for his long-running performance as Marshall on the beloved sitcom How I Met Your Mother. He also played Jason in the big-screen feature Knocked Up (2007), Judd Apatow's uproarious follow-up to The 40-Year-Old Virgin. Fresh off his success in Knocked Up, Segel parlayed his newfound wide-scale popularity into the ultimate chance to showcase his skills, writing and starring in the side splitting romantic comedy Forgetting Sarah Marshall (2008), alongside Kristen Bell, Mila Kunis, and Russell Brand.The massively succesful film also featured a supporting performance by funnyman Paul Rudd, who reteamed with Segal for 2009's buddy comedy I Love You, Man. Having found a niche with audiences, the actor next picked up another tonally similar comedy, appearing with Cameron Diaz in the sharp witted, hard-R rated Bad Teacher in 2011. Later that same year, Segal showcased his talents on both sides of the camera yet again, writing the script for a reboot of Jim Henson's beloved Muppets, and starring in the film alongside the furry stars as well. As Segal geared up for 2012, he signed on to star alongside Emily Blunt in the romantic comedy A Five Year Engagement.

Trivia: Born March 24, 1974, in Washington, D.C., Hannigan became a TV commercial veteran following her family's move to Atlanta. From the age of four, Hannigan appeared in a steady stream of commercials, including ones for Oreo and McDonald's. At the age of 11, she moved to Los Angeles to pursue a career in film and television. She made her big-screen debut in the 1988 film My Stepmother Is an Alien, as Dan Aykroyd's daughter. The following year, she won a regular spot on the short-lived sitcom Free Spirit and acted in a variety of television miniseries and sitcoms (including Roseanne and Picket Fences) until 1997, when she won the part of Willow on Buffy.The show proved to be an unexpected success among critics and viewers alike, and paved the way for Hannigan to appear opposite Tom Everett Scott in the 1998 comedy Dead Man on Campus. American Pie followed the next year, giving Hannigan wider recognition and making her an unintentional poster child for band camps everywhere. She would return for sequels in the franchise, but Hannigan would also become just as well known for her subsuquent role on the popular sitcom How I Met Your Mother.

Trivia: Neil Patrick Harris made his first splash playing a 16-year-old doctor in the Steven Bochco television series Doogie Howser, M.D. (1989-1993). Following the series' demise, the young adult actor laid low for a few years, appearing in films like Starship Troopers and Shakespeare's Sister. Harris second act would come in 2004, however, when he played a hilariously insane, fictionalized version of himself for the stoner comedy Harold and Kumar Go to White Castle. Harris would follow this up with a starring role on the hugely popular, left of center sitcom How I Met Your Mother, playing beloved rake and ladies' man Barney.In addition to his film and television career, Harris has also had a successful career on-stage. In 1997, he wowed California audiences playing the lead in the popular off-Broadway musical Rent.

Trivia: Born April 3rd, 1982, model-turned-actress Cobie Smulders grew up in her native British Columbia and commuted regularly from Vancouver to Los Angeles while looking for assignments. Smulders reportedly secured a work visa thanks to her first major role: that of Robin, the charming TV reporter whom lead character Ted Mosby (Josh Radnor) falls in love with on their very first date, on the sitcom How I Met Your Mother (2005). Before that, she had been a regular on the adventure series Veritas: The Quest and had appeared several times on The L Word (both series were shot in Canada). Her resumé also includes minor feature appearances in the Chris Klein comedy The Long Weekend (2004, as Ellen) and the Rock-headlined actioner Walking Tall (2004, as the Exotic Beauty). The actress continued to find success with How I Met Your Mother, and appeared as Agent Maria Hill in 2012's blockbuster The Avengers.

Trivia: Bob Saget offers living proof that it is possible to dramatically (and aggressively) alter one's own show-business image in mid-act. This deceptively clean-cut writer/actor/comedian began his foray into televised entertainment typecast as a "family-oriented" comic actor, and then shocked nearly everyone by emerging as a popular "blue" comedian with raunchy standup gigs, delivered from such venues as Glitter Gulch. Throughout, Saget managed to achieve considerable success in each venue, albeit among radically different demographics.A graduate of Pennsylvania's Temple University, Saget originally planned to pursue medical studies, but a brush with the performing arts convinced him to head in that direction instead. Following a brief appearance as a doctor in the Richard Pryor-Michael Apted medical farce Critical Condition (1986), Saget achieved broad recognition in 1987 when cast as genial family man Danny Tanner, a widower and father of three, on the saccharine sitcom Full House (1987-1995). Two and a half years into that program's run, Saget concurrently turned up on another program, America's Funniest Home Videos, which -- per its title -- featured the comic actor emceeing a seemingly limitless series of humorous amateur video clips sent in by folks around the country -- in a contest that issued cash prizes for the very best. Videos, like Full House, instantly scored with the public when it bowed in January 1990; Saget remained with the series until 1997.Beginning immediately around the time that Full House wrapped, Saget started branching off into a variety of directions; he helmed several features, including telemovies (For Hope, Jitters) and at least one theatrically released comedy (the 1998 Dirty Work), but placed his strongest emphasis on standup. The performer hosted Saturday Night Live, contributed a routine to Comic Relief, and headlined a series of standup comedy specials on pay cable that were -- as indicated -- definitively for adults. He also contributed a memorably scatological and raunchy routine to longtime friends Paul Provenza and Penn Jillette's standup documentary revue, The Aristocrats (2005). (The routine was prefaced by Saget's ironic admission, "Some people think I have a reputation of being a dirty comedian...," and intercepted by his tongue-in-cheek request to have a copy of the video of the routine, to send it to the kids on Full House.) Saget's 2007 directorial effort Farce of the Penguins (2007) skewered the popular nature documentary March of the Penguins (2007) with raunchy voice-overs (by an all-star cast) placed atop nature footage of penguins in the wild. Meanwhile, beginning in 2005, Saget signed for a voice-only role on the sitcom How I Met Your Mother. He provides the older voice of the lead character, Ted Mosby, as he tells his two children the story of how he came to know their mother, effectively serving as narrator for the show.

Trivia: Moved to Los Angles at 13 to pursue acting and debuted a year later as Colleen Connelly-Carlton on The Young and the Restless. After recurring roles on How I Met Your Mother and Desperate Housewives, she joined the cast of the CW's Nikita as a budding assassin. In 2010, she appeared on the big screen in the comedies Hot Tub Time Machine and Kick-Ass. Is an accomplished tap dancer.

Trivia: Big break was landing the role of Petey Pitt on the Fox sitcom The Pitts. Had a recurring role as Larry on That's So Raven. Listens to the story of How I Met Your Mother as Future Ted's Son. Has a production company called YUTE Productions.

Trivia: Kal Penn qualifies as one of the very few Indian-American actors of Gujarati heritage working in Hollywood. He was born Kalpen Suresh Modi on April 23, 1977, in Montclair, NJ, to an engineer father and a mother employed as a fragrance sampler for a perfume manufacturer. Modi bravely and intelligently cut against the grain of social expectations as a child, rejecting the prompting of his peers to join the soccer team, and instead joining the school drama team. Though allegedly mocked by classmates for his decision, Penn changed everyone's mind with his performance in a school production of The Wiz, and received a standing ovation for his work in that production -- no mean accomplishment for a beginner. During elementary school and junior high, Modi felt struck, again and again, by the crass Indian stereotypes perpetuated in Hollywood films, specifically in movies such as Indiana Jones and the Temple of Doom (1984) and 1986's Short Circuit, in which Caucasian actor Fisher Stevens plays the Indian-American Ben Jabituya for comic relief. Quietly vowing to work against this trend, Modi actually spent years attaining the box-office clout to make it happen. After his secondary school education (first at New Jersey's Howell High, then at Freehold Township High), Modi trained intensely as a dramatist on the Manhattan theatrical circuit, then attended UCLA as a drama major in the mid-'90s, and simultaneously started to land television parts right and left, in such series as Buffy the Vampire Slayer, Sabrina, the Teenage Witch, and Spin City. At about that time, he took the advice of friends and family, and -- though initially reluctant to do so -- anglicized his name, changing it to Kal Penn. As a result, he later reported, job offers escalated by 50 percent.Penn made his feature debut coming in the 1999 culture-clash drama Freshmen. A supporting role in the independent romantic comedy American Desi (2001) quickly followed -- ironically, an exploration of race and identity, about an Indian-American boy, Krishna (Deep Katdare), who moves away from home and changes his name to Kris to disguise his ethnicity, but finds himself saddled with several roommates of like heritage. Penn plays Ajay, an Indian student who has immersed himself in black ("Afrocentric") behavior. The film received extremely limited U.S. theatrical bookings in the spring of 2001 and fair reviews from the critics who saw it. Penn then jointed the cast of the Animal House-cloned gross-out farce National Lampoon's Van Wilder (2002), about a seventh-year senior (Ryan Reynolds) threatened by his father's (Tim Matheson) decision to cut off his seemingly unlimited allowance. Widely drubbed as unfunny, the picture did embarrassing box office and opened and closed in one month, but its A-list issue nonetheless gave Penn (who plays Van's Indian friend, Taj Mahal Badalandabad) with his highest-profile exposure to date. Penn's onscreen activity escalated meteorically from 2003 through 2006, with the young actor averaging around seven or eight first-run features per year, and ascending to higher and higher credit billings. Most notably, he co-starred as Kumar (alongside fellow Gen-Xer John Cho) in 2004's stoner comedy Harold and Kumar Go to White Castle, a surprise sleeper hit (and recipient of many enthusiastic notices) about two buddies, an Asian-American banker and an Indian-American medical student, whose unstoppable quest to find some White Castle hamburgers gives way to an epic road trip. Penn also delivered a brief supporting turn as Stanford, a henchman of Lex Luthor (Kevin Spacey) in 2006's Superman Returns. Meanwhile, Penn made an indelible impression on the small screen as well, as Harrison in the 2004 NBC 9/11 NBC drama Homeland Security. Penn was less effective in the ill-advised 2006 sequel National Lampoon's Van Wilder: The Rise of Taj, an installment that -- per its title -- finds Penn's Taj Mahal Badalandabad carrying Van's off-the-wall hijinks to Camden University in England. Penn subsequently signed on for an additional sequel, 2007's Harold & Kumar Escape from Guantanamo Bay, which finds the boys of the title mistaken for terrorists when they attempt to slip a bong aboard a flight to Amsterdam. That same year, Penn would headline Epic Movie, a massively scaled attempt to "send up" the Hollywood fantasy epic, Airplane! style,and join the cast of Fox's hit series thriller 24, during its sixth season. A Very Harold and Kumar Christmas followed in 2011, with concurrent roles in television's How I Met Your Mother and House guaranteeing continued small screen exposure between big screen outings.
