Craziest Moments from the Late Show with David Letterman

Drew Flashes Dave 1 of 8

David Letterman's turn at the desk of The Late Show is nearly over and it's been a long, wild run. Here are just some of the craziest moments that ever happened on the show. How many of them did you see?

In 1995, Dave was conducting what appeared to be a normal interview with a young Drew Barrymore when she suddenly found out it was his birthday. She decided to give him a gift by jumping up onto his desk, doing a sexy little dance, and flashing him in front of a live studio audience. Dave was noticeably stunned and it has gone down as one of the craziest moments to ever happen on the show.
