Celebrity Quiz: David Letterman

Letterman got his start as a local news anchor and weatherman in Indianapolis. He was known for a few on-air hijinks, including reporting weather for fictitious cities.

A morning comedy show! That's right, a 90 minute morning comedy show. The show was a ratings disaster, and didn't even make it a year, but it did pick up two Emmys!

Stupid pet tricks! The comedy sketch originated on Letterman's morning comedy show and successfully made the transition to both his late night shows.

Bill Murray! Murray was Letterman's first guest on NBC's Late Night with David Letterman, and was a guest on the last episode of CBS's Late Show with David Letterman.

Earl Hofert! More often than not, when Letterman is in a show or movie, he's playing himself. But in the rare chance that he's playing someone else, like in Cabin Boy, he uses his grandfather's name, Earl Hofert.
