A repairman is walking through a mental institution.
He comes up to the first room and sees a man swinging an imaginary baseball bat.
"What the hell are you doing?" he asks. "I'm Babe Ruth. As soon as I hit a homerun I'm out of here," replies the man.
The repairman wishes him well and continues on his way.
In the next room, there's a guy swinging an imaginary golf club. "What the hell are YOU doing?" he asks. "I'm Arnold Palmer. As soon as I make a hole in one I'm out of here!" replies the man.
The repairman shakes his head and comes up to the next room.
There's a guy sitting naked balancing a peanut on the tip of his dick.
"What the hell are you doing!" he asks.
"I'm fucking nuts, I'm never getting out of here!
