I often wish we had prehensile tails. Just think of the fun you couild have with them: as a shooting stick at games, to fend one off the wall when staggering drunk, to hold an extra weapon in combat, during sex ... The possibilities are endless! :-)

Hmmmmmm - cosmetic surgery - cross species nerve grafting - advanced tissue rejection meds and a willing spider monkey. Other benefits - we could answer the phone or scratch ourselves while we type code!:)
