Hmm what would I give my left nut for...probably not much, being really famous/rich but thats about all i can think of. Maybe being a phenomenal skier.
I think the best bang for your nut would be something really expensive like a house. That way you could sell it, buy a new nut, and still have enough left over to buy a cheaper house and a ferrari.
what store do u go to to get a left nut. I dont think u can just replace them. There are organ donors but I dont think u would want or can get some dead dudes nut.
