Conan O'Brien's third talk show, Conan, will come to an end tonight, and ahead of the final episode, he was joined by an old friend to conduct his TBS exit interview. That friend? Homer Simpson. Shortly after breaking into TV as a writer for Saturday Night Live, O'Brien left NBC for Fox, where he would write on The Simpsons. His time there wasn't especially long, because he would be called on to host his first late night show in 1993, but O'Brien is credited with writing some of the show's best episodes, including the best-episode-ever contender "Marge vs. the Monorail."
