A man was staggering home from the pub one night very drunk, when he stumbles over something on the ground. Upon closer inspection he notices it's a lamp. So he picks it up and gives it a rub and out pops a Genie.
"I'll grant you one wish" Says the genie.
The man was a bit skeptical so he says sarcasticly, "I wish I could piss Jack Daniels"
The Genie grants his wish and sure enough, when the man pisses, Jack Daniels comes out.
Excited, he races home to his wife and exclaims "I can piss Jack Daniels. Get me a glass, we're having a drink!"
"why only one glass?" the wife asks.
"That's for me, you can drink it from the bottle!", He replies.
