The look of complete disappointment and horror his face when his side piece was making him jealous by going over his main interest's past was hilarious when you contrast to how happy he was when he was initially talking to the lunch counter guy.

The look of shock on the lunch counter guy's face when the side piece was finished talking was nice as equally top notch.

Of course having Gamby throw the toothpick that was in his mouth into the side piece's lunch tray was a perfect way to top off the scene.
