Prior to SNL, he was best known as the announcer/sidekick on MTV's 1980s game show Remote Control. Following his departure from SNL, Quinn went on to host Comedy Central's late-night panel show Tough Crowd with Colin Quinn, where he and a panel of New York's big names in stand-up comedy discussed and debated news stories of the day. Notable film work includes his role as Dooey in A Night at the Roxbury, Dickey Bailey in the Grown Ups films, and playing Amy Schumer's father in the film Trainwreck.
