Rickover = crazy
I read a book on Rickover. He would have a sub commander sit in a chair before him that he had rigged that had 1 leg shorter then the others then pepper him with questions on submarines.
Wiki:
Rickover tells one applicant he has 10 seconds to make him mad or flunk the session. The midshipman hears Rickover tick down the seconds, then suddenly sweep’s half the contents of Rickover’s desk onto the floor.
“I’m mad,” Rickover concedes before hiring the young officer.
