On the "Comedian" DVD, one of the deleted scenes is of Jerry at a Porsche GTG. He's walking around looking at cars and parts, chatting with other guys. The commentary track says that they cut the scene because it really didn't fit the movie, but they were tempted to keep it because of one Jerry joke:
"It's all about social ineptitude. There's not a person here (Porsche GTG attendees) that can conduct a conversation or eat a meal without the food falling out of their mouths. Biggest losers in the world . . . and I'm one of them."
