That's pretty cool an'all, and i'ma let him have his moment, but I've had worse.
This one time in the alps when I was 12 I was kidnapped by alien gypsys but they were then attacked by flying nazi vampire beagles, where I was shot in the legs and had my arm bitten clean off, which was then used to beat me to death. But I had cleverly realised how hard I was, so being the better man I ignored it all until they were done and then just walked that shit off, and grew myself a new arm by the power of thought. Then I casualy rode home on my ninja scootech.
I even travelled through time and space avenging the incident and destroying all possible traces. Which is why you'll never find proof this happened. Because other than extremely hard, i'm very, very thorough.
