All-powerful genie
 

While he was rooting around in the basement, a man found a magic lamp. When he rubbed it, a genie emerged in a huge cloud of pink smoke.
"I am the all-powerful genie. I shall grant you one wish." The man thought about this, and decided that if there was one thing he couldn't get enough of, it was wine.
"I wish I could pee wine. That's my wish."
"Granted." And the genie disappeared. Later that day, the man's wife came home to find her husband naked, holding a glass.
"Why only one glass?" asked her wife.
"You're drinking out of the bottle tonight."
