The Simpsons by far, but I'm referring to the older episodes mostly. Then South Park, followed by Family Guy. Family Guy is really funny in moments, but when your humor solely consists of thinking of stupid crap that makes no sense, and has nothing to do with the story (i.e. "that reminds me of the time we sodomized a goldfish with a french fry" or some such nonsense), its hard to place it on the same level as those classic, brilliant Homer moments.
