Controversial when first produced (Sinn Fein types felt it depicted the Irish as glamorizing violence so they, um, rioted at the premiere), it stands today as one of the world's classic comedies.
A man walks into a bar. He announces he has killed his father with a shovel. "There's a daring fellow" is the response, and the folks in the bar offer him drinks and a place to stay, while women vie for his attention. "I'm thinking this night," he muses, "wasn't I a foolish fellow not to kill my father in the years gone by?" The next day his father shows up with a bandaged head and a blazing temper.
