ok - i love the simpsons - i always will. But latley - they have really lacked. And it is not all their fault. The standards for cartoons have sky-rocketed in the past 5 years. It used to be the Simpsons, and that was it - nobody could touch them. Now you have South Park, Family Guy, American Dad (which is not crazy funny - but you have to respect their balls - they drop at least one very edgey racist joke every episode), And don't even get me started on the slu of shit on the Cartoon Network's "Adult Swim." All the heat has pushed the simpsons into a different direction with their humor, and it is not really working for them. I'm afraid I would have to say Peter Griffin. I have laughed so hard to the point of almost pissing myself more times then I can count while watching Family Guy. And Homer was never my favorite character on the Simpsons anyway.
I bet you didn't expect such a long ass answer for a question that only needs to be responded with two words, huh?
