Here's why I figured the yo mamma joke contest would've been in character. This comic, which you have confirmed in-character for him, shows him to be a smart ass. And, aside from getting himself whipped, he hasn't demonstrated any seriously insane behaviour in this plot (or any other ABR plot yet, if I recall correctly). I know you told me he was crazy, but you also said it was only when his hair was down. I figured he was a non-comprimising hero/smartass at all other times.
Either way, I'm gald to see that my comic was enjoyed.
