Wow. I don’t think they do this anymore in schools. I can’t believe I found this. I don’t remember receiving any kind of training like this (other than for a fire drill). “The rude, clumsy puppet Mr. Bungle shows kids how to behave in the school cafeteria – the assumption being that kids actually want to behave during lunch. This film has a cult following since it appeared on a Pee Wee Herman HBO special.” The clip is in the public domain. You can watch it on YouTube here.
