There was this guy in a mental hospital. All day
long he had his ear to the wall, listening. The doctor would watch this guy do
this day after day.
The doctor finally decided to see what the guy was listening to, so he put his
ear up to the wall and listened. He heard nothing.
He turned to the mental patient and said, "I don't hear anything."
The mental patient said, "Yeah, I know. It's been like that
for months!"
