"PEANUTS!" joke

A doctor at an insane asylum decided to take his patients to a baseball
game. For weeks in advance, he coached his patients to respond to his
commands. When the day of the game arrived, everything seemed to be
going well.
As the national anthem started, the doctor yelled, "Up, Nuts!"and the
patients complied by standing up. After the anthem he yelled, "Down,
Nuts!" and they all sat. After a home run he yelled, "Cheer, Nuts!" and
they all broke into applause and cheers. Thinking things were going
very well, he decided to go get a beer and a hot-dog, leaving his assistant
in charge.
When he returned there was a riot in progress. Finding his assistant, he
asked what happened.
The assistant replied, well...... everything was fine until some guy walked
by and yelled, "PEANUTS!"
