In Monty Python's Dead parrot sketch when John Cleese returns to pet shop from the railway station in Bolton, he's having this dialog with Michael Palin:


  J.C.: I understand this is Bolton.
  
  M.P.: Yes.
  
  J.C.: But you told me it was Ipswich!
  
  M.P.: It was a pun!


Then Cleese turns back and starts to look around like crazy. Why would he do that? I thought a pun was a kind of word joke.
