Gassy Uranus

Alright, listen up, buttercup. This joke is all about Uranus, which is a planet. Now, "gassy" means full of gas, like when you eat too many beans and fart a lot, which you probably do since you ain't got no brain. But Uranus is ALSO full of gas. Get it? Gassy planet! You probably think farts are funny because you're dumb as a brick.
