Michael O'Donoghue

Michael O'Donoghue wrote for National Lampoon during the underground humor magazine's 1970s glory days. That led to a writing job on the premiere season of Saturday Night Live, where he appeared on-camera in some of his own sketches. Revered for his oddball and subversive humor, O'Donoghue became a kind of elder statesman for the show. He also wrote the movie Scrooged.

Extra credit: O'Donoghue had bit parts in the movies Manhattan (1979, with Woody Allen) and Wall Street (1987, with Michael Douglas)... Another celebrated National Lampoon writer was Douglas Kenney.
