Mo Collins

A longtime student of improv and master of disguises, Mo Collins is best remembered for the rotating cast of characters she created on the late-night sketch show "MADtv" (Fox 1995-2009). Hailing from the Midwest, the versatile comedian never completely lost her accent and worked the persona into her characters and stand-up. After leaving the show, Collins made numerous guest appearances in various films and sitcoms, most notably playing the gossip-hungry local talk show host Joan Callamezzo in "Parks and Recreation" (NBC 2009-).
