Disturbingauctions.com has a list (a bit out of date) of bizarre and often hillarious items that people have put up for sale on eBay.
Some of the items are tacky, some are disturbing, but most are just weird and delightful.
This also reminded me about the Reflectoporn stuff I read about in the Register a while back, where people have posted photos of things for sale on eBay that perhaps revealed a little more than they meant to (or not as the case most probably is.) The phenomenon merited an entry on Snopes.com.
