So, as you can see by the results of the poll in the previous post, most people think of Brent's chin as being weaker-than-average.
I bring this up because of this image in Maid of the Mist:
Brent's chin is even weaker than usual here. Maybe it was a slip of the Cintiq pen.
I also bring it up because I wanted to make sure that the following panel is the joke I actually thought it was, despite some commenters thinking that Jade was being 100% sincere when she told Brent he had his father's chin (I don't think so).
This is still my favorite drawing of Brent, partly because it reminds me of Terry Colon's work :)
