Blonde ambition

A man is driving down a country road, when he spots a blonde standing in the middle of a huge field of grass.

He pulls the car over to the side of the road and notices that the blonde is just standing there, doing nothing, looking at nothing.The man gets out of the car, walks all the way out to the blonde and asks, “Ah excuse me, but what are you doing?” The blonde replies, “I’m trying to win a Nobel Prize.”"How?” asks the man, puzzled.

”Well I heard they give the Nobel Prize to people who are out standing in their field.”
