Manhattan. The 113rd floor of a skyscraper. A restaurant.

At the table beside the window sat a man dressed in black and quietly sipped a whisky on the rocks.

Another man came to the table, asked whether he might sit down and following an icy nod took a seat.

As he drank quietly and prolifically, the man in black spoke: "You know, man, at the height of the 133rd floor, the wind is so strong that if you jump out of the window, it will swirl you back here."

The other guy cast an untrusting look at him. In order to prove himself right, the man in black jumped to his feet, threw himself out of the window and in five seconds flew back in.

"You see, I'm not lying," the man in black said. "Now it's your turn. You can try by yourself."

The poor man walked towards the window embarrassed, jumped and flew... but this time the gravitation worked and he smashed to the ground.

At the same time, up there on the 133rd floor the bartender approached the man in black and said angrily: "You know, Batman, when you get drunk you turn really mean!"
