Yes, humor has a place. There's not a ton of funny characters here, but I run one as Engy and Guppy is also very funny (although its a certain kind of irreverent offensive humor that I don't think would fit the Mario Brothers mold). I actually think it's harder though to be truly funny as opposed to being serious and intense. It demands a certain degree of timing, punchiness, and finesse and you'll have hits and misses for sure, kind of like a standup act. It's something you really have to practice at, and I think it demands more "outside the box" thinking than cutting a serious promo or a trash talk.

Funniest guy I've ever read was in a place called Hardkore World years back named Matthew X. He once dumped a bag of puppies on a token goth character so they would lick away all his sadness. I lol'ed.

I've also always felt that if you're going to go with character development, have it tie into the wrestling end of it in some form or fashion. Maybe recount a story that somehow relates to a challenging match. Or have a stressor going on that could effect in ring performance. I've always felt that the best writers tie everything together into a cohesive whole. No disrespect to guys like Duke, but when people spend the majority of their wordcount basically just telling a story that has nothing to do with XWF whatsoever that always feels disjointed to me, and undercuts the fact that the fed should be front and center.
