A man walks into a bar and orders a drink. Another man walks up to him and says to the first, “Hey. The special of the day lets you defy gravity! Watch!” He walks over to the window, steps out, does a couple of spins in the air and comes back in.
The first man says to the bartender, “I’ll have the special of the day!” The bartender gives him the drink and the man drinks it. He then walks over to the window, steps out and plummets to his death.
The bartender says, “Superman. You can be a real jerk when you are drunk!”
