Super Power Beer's Deadly Effect

A man walks into a rooftop bar and takes a seat next to another guy. “What are you drinking?” he asks the guy.

“Super Power Beer,” he says.

“Oh, yeah? I doubt it?”

Then he shows him: He swigs some beer, dives off the roof, and lands with no damage whatsoever. He walks back into the bar.

“Amazing!” the man says. “Let me have some!” The man grabs the beer. He drinks it, jumps off the roof — and falls 15 stories to the ground.

Splat.

The barman says. “You know, you’re a real idiot when you’re drunk, Superman.”
