Maybe you haven't noticed, but "David and Goliath" claymation cartoons are boring. There is a reason why you don't see a lot of them in syndication; most people would rather go bobbing for french fries rather than watch an episode.
What is funny, is watching someone else suffer for making poor choices. Simpsons, SouthPark, Roadrunner, Bugs Bunny, Daffy Duck, pretty much every comedy made since the 40's exhibits this. Even "Leave it to Beaver" would have Wally, or the Beav make a poor decision. Then we would laugh as they suffered the consequences. The more the world changes, the more things remain the same.

I'm inclined to agree, depending on what one means by "poor." To teach right from wrong (Beaver, for instance), you show that doing the wrong thing brings you to grief. You can make that hilarious (Lucy).
To me, at least, it's no longer funny when popular media invert the values and make fun of people for being what we used to call straight or square.
