My favorite Norm joke was "A director filming a documentary on juvenile violence was savagely beaten by teenagers. When asked why they attacked the director the assailants said they had nothing against the man, they just love irony."One of the best weekend update jokes ever.
I also enjoy one that goes something like this
“A little wrinkle in the trial for O.J. the other day as Johnny Cochran put on the cap that was found at the scene of the murders. O.J. likely hurt his chances when he got up and shouted “hey, careful with that, that’s my lucking stabbin’ hat.”
