You know that assumption about men who drive very big or fast cars are probably compensating for the size of their "manhood?" Well, one guy changes that whole idea by actually selling a testicle for a Nissan 370Z.

I know selling a testicle sounds illegal, but Mark Parisi is telling everyone he is "donating" his testicle to science. That's totally legal. He announced his plan to share his nut with science on the CBS television show, The Doctors.

Parisi will be given $35,000 as a "standard fee" for medical research, as long as the research is approved by the Food and Drug Administration. He plans to use his compensation money to buy his dream car.
