Career: During his gap year, Whitehall decided to pursue a career in stand-up comedy. He juggled studying the history of art at Manchester University with gigs. In June 2008, he presented the first week of Big Brother's Big Mouth on E4. He followed this up with appearances on Channel 4's 8 Out of 10 Cats and from then on, became a TV fixture. Whitehall dabbled with acting as a child (he appeared, age nine, in the series Noah's Ark and claims to have auditioned for Harry Potter), and returned to it as an adult with the sitcoms Fresh Meat and Bad Education. He's a regular competitor on Sky1's sports quiz A League of Their Own, appears on various panel game shows, and continues to do stand-up. He also co-hosts a chat show with his dad on BBC Three.

Career: Cleese's showbiz break came with The Frost Report. By 1969, he and Chapman were working alongside Eric Idle, Terry Jones, Michael Palin and Terry Gilliam on Monty Python's Flying Circus, which made them household names. He left the group in 1972, although they reunited for several films. In 1975, Cleese and his then wife Connie Booth wrote and starred in Fawlty Towers, which was a worldwide hit. Projects since include A Fish Called Wanda, which he co-wrote, two Bond movies, and two Harry Potter films. He has also appeared in 3rd Rock from the Sun and Will & Grace. His stand-up show, The Alimony Tour, proved hugely popular in 2010; his most recent film, God Loves Caviar, was released in 2012.
