A woman walks into a bar on the top floor of a skyscaper and asks the bar tender for his best drink.

A man at the end of the bar spoke up and says 'you gotta try the beer. Its magic! I'll show you.' He grabs his beer, chugs it, runs over to the window and jumps out. The woman gasps and runs to the window so see the man fly around the building and right back in. She is so amazed she gets a beer, chugs it down, jumps out the window, and SPLAT, hits the ground
The bar tender looks up at the man and says, 'Superman, you're an asshole when you're drunk.'
