Pondy was an honourable mention for me. I know too many people like Pondy irl which makes him a little less funny but he is funny (and the coolest, as you mentioned)
Da Maniac, good call! I couldn't place the character at first, was thinking Psycho Pete and then thought "a favourite?!", and then searched the name. I love the boys' realization that Da Maniac has more baggage than they first thought when they idolized him in the ring
Artemis. She's her own level of crazy and confident that the antics of the gang which usually ruin the lives of all those encounter just bounce off her.
Totally agree and very well put! I especially like when Artemis foils Dee's desire to look like a classy group of girlfriends. "Don't talk about your bleached anus!"
Out of the gang: Artemis or the McPoyles. Jimmy Simpson is always hilarious, "You will call her!" (And when Ryan takes off his "disguise" at the wedding.)
