Why would someone want their lower arm sawed off?

I assumed he was playing the game as well. His challenge was to lose the arm in order to get the prize. Guess he needed the cash pretty badly.

Oh, goodbye mama. I'll never do dishes again.

I think he was also a contestant. I assume they were going to reattach his arm back since Elliot put his arm in a bag filled with ice, which he later gave to the nurse at the hospital


-When you're jaded enough everything can seem like a cliche-

He was obviously also playing the game.
