David Letterman is an American comedian, known for hosting the Late Show with David Letterman on CBS since 1993. Letterman's ironic, often absurd comedy is heavily influenced by former Tonight Show hosts Steve Allen, Johnny Carson and Jack Paar. Letterman has been a fixture of United States late night television since his 1982 debut on Late Night with David Letterman; only Johnny Carson, one of Letterman's idols, has had a longer late-night hosting career.

Letterman is also a television and film producer; his company Worldwide Pants produces his late-night show and the show that follows his on CBS, The Late Late Show With Craig Ferguson. Worldwide Pants has also produced several prime-time comedies, the most successful of which was Everybody Loves Raymond, currently in syndication.

Born April 12, 1947 his primary personality traits are represented by the Chinese Zodiac elemental animal sign, the Fire Pig. The Fire Pig is a very different kind of Pig, not laid back in the least. He tends to charge into situations wearing his heart on his sleeve, all emotions in full gear. This tendency to rashness and emotionalism occasionally irritates his friends and family. Still, everyone knows he is good-hearted and will forgive his these excesses. Often cherished for his can-do spirit and sincerity, he tends to be a big winner---or loser.
