Those two guys who keep telling the jokes
How many times is Howell in a room and overhears these two guys telling their racial jokes? That to me is the funniest part of the movie, I mean the number of times he comes on them they must be sitting there telling those jokes all day. I wonder if the directors meant to have that part be so obviously unbelievable, or if it was just a way to get more of those guys jokes in there and help the story?
Either way it works for me, I can't stop laughing when those guys have a scene because no matter where or when he sees those two guys they're telling one of those jokes. They must tell them in their sleep.
