joke of the day

A guy gets on a plane and sits down next to a beautiful girl, wonders if he could make a pass. So he´s like: "Hello, maybe our journey will pass quickly if we talk together?" The girl puts down her book and says, "well, what do you like to talk about?" The guy thinks for the second and goes, "nuclear energy, perhaps?" "That could be interesting," the girl says, "but before we start, let me ask you a question. Deer, horse and cow, they all eat the same stuff, grass. But their poo is very different. Deer craps small, round shaped objects, while cow´s poo is more watery and the horse´s is a dry turd. Do you think you are able to explain it?" The guy´s face goes like this :yow: and he says he doesn´t know. "So tell me," the girl replies, "how is it possible that you feel actually accomplished enough to talk about nuclear energy, when you don´t know shit?"
