Pirate's Steering Problem

A pirate walked into a bar with his ship's steering wheel hanging off his pants. The bartender says, "Hey! What's with the steering wheel?" The pirate says, "I don't know but it's driving me nuts!"

Explanation

Experiment

The humor comes from the literal interpretation of the phrase 'driving me nuts.' The pirate is wearing a steering wheel, which is used for driving, and he says it is 'driving' him crazy. It's a pun on the literal and figurative meaning of the word 'driving'.
