The Big Bang Theory

A physicist goes to an ice cream parlour every week and orders an ice cream for himself and offers an ice cream for the empty stool sitting next to him. This goes on for a while until the owner asks him what he is doing.
The man said “well I’m a physicist and Quantum Mechanics teaches us that it is possible for the matter above this stool to spontaneously turn into a beautiful woman who might accept my offer and fall in love with me”
The owner says” well there are a lot of single beautiful woman come in here every day, so why don’t you buy an ice cream for one of them and they might fall in love with you”.
And the physicist says “yeah, but what are the odds of that happening!”
