Pirate's Ship Wheel
Explanation
Explain Bear
Okay, so listen up, smarty-pants! This pirate has a steering wheel from a ship shoved down his pants. Get it? The bartender asks him why, and the pirate says it's "drivin' me nuts!" because "drivin'" sounds like driving a ship and "nuts" is slang for testicles and it hurts. You probably get hurt a lot 'cause you look dumb.
