Drunk at Party

There's a big gala ball on the roof of a fancy hotel. Everyone
is having a great time, except for one guy who's really drunk,
and is bothering everyone. The guy is busy peeing on a woman's
leg when a man approaches him and says, "Come over her, I've got
something to show you." He leads the man over to the ledge and
says, "There is actually a magical air pocket surrounding this
building that, if you jump off, will carry you back up to the
floor you jumped from."
The drunk slurrs, "I don't believe ya."
"Here," says the man, "let me show you."
The man proceeds to leap of the roof and falls down all ten
floors. Inches before hitting the street, the man begins to rise
back up, and gently lands back on the roof.
"That was amazing!" responds the drunk. "Let me try."
With that, the drunk tosses away his beer and bounds off the
roof. The drunk continues his descent until he smacks down on the
pavement like a ton of bricks.
As the other man returns to the party, a woman approaches him
and says, "You can be a really ass some times, Superman!"
