THEE VERY BEST JOKE I'VE EVER HEARD IN A MOVIE IS FROM 'Catch Me If You Can'.
"Knock, Knock."
"Who's There?"
"Go Fuck Yourselves!"
Another Good Joke Is From Watchmen(2009). "I heard a joke once: Man goes to a doctor. Says he's depressed. Says life is harsh and cruel. Says he feels all alone in a threatening world. Doctor says. 'Treatment is simple. The great clown Pagliacci is in town tonight. Go see him. That should pick you up.' Man bursts into tears. Says, 'But doctor... I am Pagliacci!' Good Joke! Everybody laughs! Roll on snare drum. Curtains!"
