A comb I've had since 7th grade(I was what... like 13, so 8 years). I had a stuffed alligator that I had since I was born but some goddamn roomate in Hawaii stole it!
I've got some very old things I've dug up from my garden and the surrounding fields...don't know how old, but they are pretty old...the ground around where I live was the site of a very big Saxon battle...so imagine the things still buried...
God, I don't really know. I've got an Alice Cooper shirt from the early 80's. I suppose I still technically own my Mercedes, which is from 1979. I don't know what else beyond that.
I say "technically" because although I never sold the car and it's last registered owner was me, it hasn't been in my possession for a period of several years. It's sitting dead at a garage in Wyoming, collecting dust.
