Two thieves broke into a bank in the middle of the night and open a safe. There was only some yogurt, but no money They tasted the yogurt. It was tainted.
The men open the next safe. There was some yogurt too, it tasted much better but again – no money.
The thieves take on another safe. And there was yogurt again “John, why don’t you go outside and look if it is indeed a bank!” says one to the other, and sits down to eat the yogurt which tastes really fresh and nutritious this time
A couple of minutes later John came. “It is definitely a bank!” “What exactly did the sign say?” “The Sperm Bank of Ohio!””
