Would say it's my best but. A man takes an elevator to the bar at the very top of the empire state building. There's only the bartender and a really muscle-y guy in a suit blowing a stack of napkins out a window, having them come through the other window and landing in the bottom of the pile. The guy comes over and says "that's amazing, how do you do that?" The man in the suit explains "the wind hits the skyscrapers right side, goes around and back up the left." "Thats insane." He says. The man in the suit says "I'll give you ten bucks to jump out that window and land on the windowsill on the other side" The man replies "that's suicide, no way" The man in the suit jumps out the window, goes down, around, back up and lands on the other windowsill. He then says "if it can carry a big man like me it can certainly carry you." The man then says "okay, I'll do it" The man jumps out the window, hits the ground and dies. The man in the suit walks over to the bar, the barkeeper says "Superman, you are one bastard when you drink" Sorry if it's complicated, English is hard for me.
