I bought an Unearthed Arcana for 5 bucks in seventh grade science class. I was always interested in the game, but didn't have access to it. I am pretty sure the guy who sold it to me stole it from a relative or friend. He was the same one who stole my 64 crayolas in kindergarten only to eat them.
Reading the book in secret, I couldn't make heads or tails of it. But by eigth grade it had been secretly tossed by my parents and instead found a friend with some of the books. We played a couple of times a strange conglomeration of things I can't now remember. But I do know my friend was very excited to learn 2nd Edition was coming out. We basically started a whole newbie campaign with a newbie DM off the 2E books when they came out.
No one had any experience or knowledge of the game, so it was rather poor, but we had fun bashing on things. It would have been 100x better, if there was a sympathetic adult around. But by that time the game's rep was in the toilet.
