Ridiculous things people sell on eBayok, u see this topic on a lot of places these day (Leno's show, webboards, dang there're even groups on different communities about this) but here are just a few that I was able to find to see for myself:
Eminem Used Condom WRAPPER
Britney Spears Discarded Cheetos Wrapper
RARE drawing of iPod prototype sketch SO COOOL!
2 invitations to a wedding I don't want to go to
4PPL3 S4UC3 (lmao at this one, [for those that don't know 1337] )
enough for today >.< can't bother looking for more :P
