There was an episode of House where this bloke wanted to donate a kidney to a stranger because it's a numbers game, his small sacrifice can help others live. Odd but not insane. Although by House's standards, very insane. House had to prove this insanity to other people. So he convinced the guy donating the kidney that he could donate other organs, and hell why not another kidney... And if he was going to die, he could donate everything and that would help hundreds of people merely for the sacrifice of just him... House can sometimes be so very smug.
