I can't get enough of these!
It'd really take an open mind to appreciate them.
I recently got a "weird movie" dvd on Ebay, and it had stuff like "Science Forum" from the 50s and talked about subjects that would seem so mundane but I was really getting a kick out of it. Also, there was one from WW2 era that was titled, "How to Give an Enema." They didn't show anything gross and although I was tickled, it was informative.
Where can I get more of these? I'm addicted!
