For sale: Used condoms made from fish swim bladders - Boing Boing: "This set of 110-year-old condoms, made from the swim bladders* of fish, are up for auction in Vienna. Delightfully, they seem to have been meant to be reusable, as evidenced by the former owner's careful tally of how many times each condom had been used. It looks as though you were only supposed to reuse 10 times."
