Stop me if you've heard this before.
A theoretical physicist walks in to a bar.....
He sits down at a table and orders two drinks.
The bartender brings over both drinks and watches as the physicist carefully places one in front of the empty chair next to him and then proceeds to slowly drink the other one.
Eventually, he finishes his drink. He waits a little longer, watching the empty chair. Nothing happens. With a sigh, the physicist leaves a tip and walks out.
This happens every day like clockwork for a month. Finally, the bartender can't contain himself anymore. "What is it with you and this extra drink in front of an empty chair?" He asks.
"Well," says the physicist. "According to the laws of quantum mechanics, it is possible a beautiful woman might appear in that empty chair. I figure if I have a drink waiting for her when she shows up, it will help break the ice."
The bartender stares at the physicist and says, "Why don't you offer one of the women at the bar a drink and see if she'll talk to you?"
The physicist rolls his eyes and says, "What are the odds of THAT happening?
