This pill allows you to fly

A man went into a bar in a high rise. He saw another man take a pill, take a drink, walk to the window and jump out. He flew around for a minute and zipped back into the bar.

As the amazed newcomer watched, the man repeated this twice more. Finally the man asked if he could have a pill. The flier said it was his last one. The man offered five hundred dollars to no avail, so he made a final offer of a thousand dollars. The man said that it was all he had on him.

The flier reluctantly gave in, took the cash, surrendered the pill, and turned back to the bar. The man took the pill, took a drink, went to the window, and jumped out only to fall to his death. The bartender walked over to the flier at the bar and, wiping a glass, said, "You sure are mean when you're drunk, Superman."
