Here in NC there used to be a law on the books with which you could charge someone with maiming you if they maliciously disfigured you. In one of the more colorful episodes of the employment of this charge, after a large bar fight, the following testimony was heard.

Billy Bob, were you present at the time of the fight? YES.
You have claimed that you could testify to the fact that Bobby Joe bit off Rufus's ear. Did you see Bobby Joe bite Rufus's ear off? No! .........after a bit of prosecutorial confusion in the court room the witness continued ................. but I saw him spit it out!
