Well, well....the state of Connecticut has been heard from. None other than Margaret the Magnificent has correctly identified Deon Richards, better known as Rudy's friend Kenny (aka "Bud"). Unlike previous Guess Who? subjects, however, Deon is still pretty active in the Hollywood scene.
According to IMBD, he went on to play on shows such as Getting By and Sister, Sister, a ton of campy horror movies (Scream 3 and Not Another Teen Movie), a teacher on the quickly cancelled show of this year, Teachers, and is now working on The Louis Armstrong Story.
Well done Margaret.
