Mr. Stein first appears in the fifth season episode Boardroom and a Parked Place, having been absent due to working at the London office (although it is revealed that he was actually in a mental institution).
He is noticeably absent-minded and has short-term memory loss, needing to be constantly reminded of his identity and surroundings. He also has a tendency to break out into song.
- Gene Wilder won an Emmy Award for Outstanding Guest Actor for this role.
