I think you've found out how to do it right. Have a bit of humour going on. Basically, make a scene FUN rather than a stressfest that nobody else enjoys.
Yeah, it's all in intention, I think. I do it to entertain myself and the people I play with (he's so fun to pick on), rather than to be an actual ass. You basically made my point much more succinctly. If you play an ass with the goal of entertaining not just yourself, but other people as well...it's not generally going to be awful. If you're doing it just for yourself, or you're playing an Entirely Serious Character from an OOC perspective, probably going to have an issue.
