Once, I had a teacher (in middle school I think) who was different than anything else.
When he taught us about the second world war, he slammed his fist into a pupil's bench and roared: "And the bastard wanted Russia!" about Hitler.... Then he slammed his flask of water into another bench, and a pupil got to dry it up, because she had talked to loud.... and we loved him. He was the craziest and funniest teacher ever. He made school fun again. Those times he slammed things around... well, we could live with it ^^
