Our shop teacher was in charge of the paddle. He was an offensive lineman for the Miami Dolphins before he blew out a knee before his rookie year.
Yeah, he laid the wood.
My Junior High metal shop teacher had a different method to command attention, his key ring weighed an easy two pounds and if you were being an ass and causing trouble or damage you would find that key missile directed right at you, he had deadly accurate aim and never quite hit any ones head, but no one wanted to give him a second chance. And you know what? We all survived with out running home and crying to mommy.
