Is it possible to bite a chunk out of your arm?

[jonnyd]

My friend and I were arguing the question of whether or not you could bite a chunk out of your arm. I believe that you couldn’t and that your brain would not let your mouth bite hard enough; that the pain would basically freeze your jaw and that you would not be able to override your brain to tell yourself to bite a chunk out of your arm. Even if there was, a billion dollar proposition bet or something, I don’t think that it is possible.

Has anyone heard of a similar situation, and/or outcome? Who is right? Is my reasoning wrong? Any and all feedback is appreciated.
