Another line in the Label Maker episode that was more funny because of its reference than being funny in and of itself was the exchange between Jerry and the dentist....something like:
Dentist: Gee thanks for the tickets. I'll have to take you out for dinner [soup?] or something.
Jerry: Nooooo! No Soup!
When he gets the label maker, the look on his face was just like the "friend" of his who gave him the suit a few episodes back. Funny..
