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?” The guy proceeds to show him: He drinks some beer, jumps off the roof, flies around the building, and returns to his seat.
“Amazing! Lemme try some of that,” the man says. He grabs the beer, downs it, leaps off the roof,
and falls 30 feet to the ground.
The bartender shakes his head and says to the first guy, “You know, you’re a real jerk when you’re drunk, Superman.”
