A Physicist Walks Into A Bar...

and orders two drinks, having one for himself and leaving the other one untouched at the stool beside him. The next day, the bartender notices that he does it again, and the day after, he does it a third time. When he does it a fourth time, the bartender finally asks him "why do you keep ordering two drinks but only having one?". In response, the physicist says "according to the laws of physics, there is a statistical chance that billions of atoms could align perfectly and form a beautiful woman sitting on the stool". The bartender then asks "why don't you just ask a woman to have a drink with you and see if she says yes?", to which the physicist replies "well what's the chance that that's actually going to happen?"
