Gregory Everett "Greg" Proops (born October 3, 1959)  is an American actor, stand-up comedian and television host. He is widely known for his work as an improvisational comedian on the UK and U.S. versions of Whose Line Is It Anyway? . He also performed on Drew Carey's Green Screen Show and played Max Madigan on the Nickelodeon sitcom True Jackson, VP .  
Proops was born in Phoenix, Arizona, and raised in San Carlos, California, a suburb south of San Francisco, attending San Carlos High School.   He attended the College of San Mateo and spearheaded the comedy duo "Proops & Brakeman". Later, he took courses in improvisation and acting at San Francisco State University though he never finished college. 
After college, he joined an improv group with Mike McShane. Both Proops and McShane impressed producers Dan Patterson and Mark Leveson, who put them on their show, Whose Line Is It Anyway? . He frequently instigated jokes concerning various idiosyncrasies and differences between British English and American English (e.g. "lift" vs. "elevator"), and would frequently banter with Clive Anderson on these matters (among others). He lived in London for four years when he was doing the show and lists McShane, Richard Vranch  and Colin Mochrie as among his best friends. After the show ended, he was recalled for the American version and was a regular "fourth contestant".
Proops also appeared in every episode of the short-lived Drew Carey's Green Screen Show , where the performers would play improv games (some of which were taken from the show's main influence Whose Line Is It Anyway? ) in front of a massive green screen.
