Conan and his hair are as lively as ever in retro 'Late Night' photos

Remember when Conan O'Brien hosted Late Night?

The current Conan host took the helm from David Letterman in 1993, manning the Late Night desk for 16 years.

Among his first-season guests were Mary Tyler Moore, Drew Barrymore, Chris Farley and Carrie Fisher, with musical performances by Radiohead, Mazzy Star and the Cranberries, among others. His now-sidekick Andy Richter also appeared on the show until 2000.

Let us go back in time, fellow Internetters. Back to Season 1 of Late Night, before that Tonight Show fiasco wasn't even a glimmer in anyone's eye.
