it's tough to say
simpsons had a fine era but i can't even stand to watch the new episodes
i love new southparks. the old ones were really lame
futurama is consistent and has the best characters ever in dr zoidberg and the zapper
and king of the hill has bobby hill who makes me lmao. and gribble
and we should not forget spongebob squarepants
family guy is kinda funny but can also be lame. the new season is awful
american dad is like a funnier family guy, but who knows how long it will last?
mission hill was excellent but short-lived
so thinking about it, the strong south park era of a couple of years ago probably made me laugh the most. but as thierry says, the simpsons has given us so freakon much. that fact simply can't be ignored, regardless of how lame every single new episode is
