"...If you're caught without it - BRICK..."

I sadly suspect that in todays politically correct world, some parent would protest that this was demeaning to his/her overweightoutofshapeunderprepared kid, an attorney or three would get involved, etc etc etc.

Kind of like metal shop in my high school. If you ever left the chuck key in the chuck of a metal lathe (without your hand on it), and the teacher saw it, you were made "creap of the week." Along with the title came the fun job of cleaning the drip pans under all of the tools at the end of the day for a week. Then, quite a few years later, some parent didn't like Little Johnny being called that. Today, same school, no metal shop at all...
