Old and New Jokes

A man was sitting at the bar in a watering hole whose selling point was that it was on top of the largest skyscraper in town. Another man walks in and asks the bartender for a Jack Daniels. He downs it, and then takes a running leap out the window. Much to everybodys surprise, he floats back up and climbs through the window back into the bar. The man at the bar is amazed and asks the man how he did it.
"Easy," says the man. "Outside this window are some very strong wind currents which can carry you back to the window."
"Wow," says the man at the bar. "I gotta try this." He takes a running leap out the window and falls to a horrible, bloody, and flat death.
"Geez, Superman," says the bartender. "You can be a real a jerk when youre drunk."
