If there was ever a perfect example of a "shit-eatin' grin" then Burton Gilliam had it going on. Kind of surprised he never had a bigger career after that performance.
John Hillerman (Howard Johnson) is still alive as well.
But I was thinking the top billed stars of the movie - Cleavon Little (who was from Chickasha), Madeline Khan, Alex Karras, and Harvey Korman.
Perhaps Gov. LePetomane will outlive us all. (If you don't know who the real "LePetomane" was, it's worth looking up. At one time, he was the highest grossing performer in Europe.)
