It reminds me of a Joke....

There were these two guys in a mental institution, and, one day, they decide that they don't like living in a mental institution. They decide to escape. So they make it up to the roof, and there they are. And they look down and they see this gap, and it's a short jump from the roof to the other roof, and then straight on to freedom. Now, the first guy, he jumps across, no problem, but his friend, he daren't make the jump. He's afraid of heights.

So, the other guy says "Look! I have my flashlight with me! I'll shine the beam over, and you can walk across, and we'll be free."

But the other guy just stares at him and says "What do you think i am, crazy?! You'd turn the flashlight off when i was only halfway across!"
