A man was sitting at the bar drinking, when a woman came up and asked what he was drinking.
He said "Magic beer."
She said "Yeah,right!"
He said "I'll prove it!"
He then jumped out of the window and flew around the building.
The woman said "That has to be a trick."
So, he did it again.
The woman said "Okay, give me a magic beer."
The woman drank the beer, jumped out the window and SPLAT!!
The bartender turned to the man and said "Superman, you're a mean drunk!"
