An oil tanker sank in the middle of the ocean, and Paddy and Mick found themselves floating around in a lifeboat.

Paddy found an old lamp in the bottom of the boat, and, secretly hoping for a genie, rubbed it.

Poof!

A genie appeared, but could only offer one wish, instead of the usual three.

"Turn the whole ocean into Guinness!" blurted Paddy, not thinking very hard.

Poof! The ocean turned to black Guinness, with a creamy white top.

Paddy stared at it. Mick came up from the other end of the boat, scratching his head.

"You've done it now, Paddy" he said. "Now we'll have to piss in the boat."
