A man walks into a rooftop bar and takes a seat beside another guy.
“What are you drinking?”, he asked.
“Magic beer”, said the second man.
“Oh yeah?”, says the first guy. “What’s so magical about it?”.
“I’ll show you”, says the second guy, who takes a swig, dives off the roof, flies around, and returns his seat.
“Amazing!”, says the first guy, grabbing the bottle of beer and taking a huge gulp. “Let me have a go!”. The first guy takes a dive off the roof and plummets fifteen floors to his death.
The barman gives a sigh and turns to the second man, and says “You know, you’re a real jerk when you’re drunk, Superman”.

Next joke?
