Jerry: What's with all the peanut butter George? 
  
George: I'm increasing my lung capacity, Jerry! I told Susanne [a party clown] I could blow up a hundred balloons in 10 minutes and now she wants me to help her at a kids party!  
  
Jerry: A kids party! George, you don't know anything about kids!  
  
later... 
  
Elaine: What happened to Susanne, George?  
  
George: Oh, that's over.  
  
Jerry: What? Why? 
  
George: I sneezed peanut butter all over a kid... 
  
Elaine: Ohhh... 
  
George: ...he was allergic. His face puffed right up!  
  
Jerry: Like a balloon? 
  
George: LIKE A BALLOON!
