Foolishly, David Letterman had tried to make a go of it in the bright light of day. The former weekend weatherman from Indiana had his own national morning television show out of New York City in 1980. But his skewed humor and barely-out-of-bed looks (the thatchy hair seemed particularly insolent) left many daytime viewers perplexed—if not, indeed, slack-jawed with incomprehension.
All that changed at 12:30 a.m. ET on Feb. 1, 1982, when NBC's Late Night with David Letterman premiered in the slot right after the Tonight Show with Johnny Carson. Suddenly the world made sense: The Hoosier had found a home, and irony-starved insomniacs had found an idol. In the two decades since, Letterman has helped reshape late-night TV and American comedy itself with crusty wit (and, lately, a little bit of hip sincerity), heroically adolescent sight gags and stupid tricks from all species. Letterman, 54—whose rechristened Late Show with David Letterman moved to CBS in 1993—hasn't announced plans to celebrate this latest milestone. But that didn't stop PEOPLE from assembling a Top 10 list of important moments from the world of Dave.
