The winds of Uranus go on and off, so you could say the wind is broken.

Listen up, buttercup. The joke is all about wordplay. "Winds of Uranus" sounds like you're talking about farts (because Uranus sounds like "your anus"). And if the wind (farts) is broken, that means you can't stop farting. It's funny 'cause it's immature, and you probably still laugh at potty jokes.
