This appears to be the case with a 17-year-old Chinese boy who reportedly decided that he would not give his right arm for an iPad 2, but he would give his right kidney.
I know, I know. It doesn't seem entirely sensible. On the other hand, you can live quite happily with just one kidney. It's a lot harder with, say, just one foot.
The way the Shanghai Daily tells it, the boy, from Huaishan City, said he couldn't afford an iPad 2 and wanted one rather badly. He said he was contacted by an online broker who told him he could get 22,000 Yuan (just under $3,400) for his kidney.
