Yeah, the Educational Archives DVDs are amazing. There are a couple of films that are more disturbing than they are funny though. I think the "More Sex & Drugs" DVD has a film about introducing mentally handicapped people to the concepts of sex and genitalia that left me a little scarred after viewing. The "On the Job" DVD also includes a couple of films that are a bit shocking, including a film about a dog who dies painfully after eating metal shavings from his can of dog food because of incompetence at the factory, and a safety film that had some graphic (for an educational movie anyway) footage of a guy being run over by a bulldozer if I remember right.
Great DVDs and it's cool that they finally started putting out box sets.
