Tom and Clark are standing on the roof of their building drinking a few beers on their break when Clark says,
“Hey Tom, did you know that if you jump off this building, after you get down so far, a draft will pull you back inside the building on the third floor?”
“Get outta here,” says Tom.
“I’m serious. Watch me,” Clark says. Clark hops off the building, and sure enough, he is taken in by the draft to the third-floor window. He takes the elevator back to the top and Tom is standing there in awe.
“I can’t believe it,” says Tom.
“I know. You should try it.”
So Tom hops off and plunges into the ground.
A doorman working below sees Tom splat to the ground and screams back up, “Superman, you’re a real jerk when you’re drunk.”
