I went to Sheridan College for animation too, with some of the guys who ended up doing that show, but I never met him. A co-animator and friend (and female) has interesting stories about John K., including how he scratched at their paper until it ripped screaming at his animators, "Draw like a man!!!" While that's a second hand heresay account, I tend to believe it, as the rumours/stories like that were not uncommon.

I did NOT know about the sexual predator stuff though.
