A man walks into a rooftop bar and takes a seat next to another guy. “What are you drinking?” he asks the guy.
“Magic beer,” he says.
“Oh, yeah? What’s so magical about it?”
Then he shows him: He swigs some beer, dives off the roof, flies around the building, then finally returns to his seat with a triumphant smile.
“Amazing!” the man says. “Lemme try some of that!” The man grabs the beer. He downs it, leaps off the roof—and plummets 15 stories to the ground.
The bartender shakes his head. “You know, you’re a real jerk when you’re drunk, Superman.”
