A guy walks into a bar and starts a drunken conversation with one of the patrons. “Hey what’re you drinking?” the patron asks. “Magic beer,” says the guy. After arguing about it for a few minutes the guy says, “I’ll prove it to you.”

They go outside and walk to a nearby cliff. The guy chugs his Magic Beer, then jumps off. Miraculously he floats back up and settles down next to the stunned patron.

The patron runs back to the bar and says to the bartender, “I want what he’s having!” pointing to the guy. The patron chugs his Magic Beer, runs over to the cliff and plummets to his death.

The guy walks back inside smiling and orders another beer. The bartender shakes his head and says, “You know, Superman, you can be a real asshole.”
