4. Willie Garson
Kevin Stone’s buddy was Carl, played by Willie Garson. It was a small role, only in seven episodes, but Garson did okay afterward. Audiences know Garson from movies like “Groundhog Day,” “Being John Malkovich,” and “There’s Something About Mary.” Garson has been consistently in several productions every year since the late 80s. He’s that guy you recognize but can’t quite place.
