>>201244It's a fan-made doujin OVA that sold a few dozen if not a hundred copies at the winter Komiket (Comiket?) one year a few years ago.
Apparently, the people that got copies guard them with their lives. It supposedly very funny, but until the owners of these DVDs spit them up, we'll never know.
If I remember what I read on other sites about it, it was Komiket 67. I don't know if that means anything for you.
