A doctor worked at a mental hospital. He wanted to take some patients to a ballgame, worked months to get them to follow simple commands, finally decided they were ready. When the star spangled banner played he said: "Stand up nuts" and they stood. When it was over he said: "Sit down nuts" and they sat. When a player got a hit he said: "Cheer nuts" and they cheered. When the umpire made a bad call he said: "Boo nuts" and they booed. He decided it was safe to leave them with his assistant & left to get a hot dog. He came back to a near riot. He asked his assistant what in the world happened. He said: "Everything was fine 'til some vendor came be and yelled 'peanuts'."
