It's Dr. Smith's first day working at that mental institution. He figures he'll check in on a couple of patiants and get a feel for the place.
So he checks into the first door and there's a guy swinging a baseball bat wildly in the air. "As soon as I get out of here I'll be back in the majors, Doc, you'll see!"
"I bet you well," says Dr. Smith, and walks on.
He checks into the next room and there's a guy jamming away on his guitar. "When I get out I'm putting the band back together and going on tour."
"Sounds like a good idea," says Dr. Smith, and he walks onto the next room.
When the Doctor opens the door he sees a man laying in bed furiously masturbating into a bag of cashews.
Dr Smith stares at him in awe. "And what are you going to do when you get out?"
"Get out?" The man asks. "Doc, I ain't ever getting out of here. Can't you see? I'm fuckin' nuts!"
