I voted for The Simpsons. Most of you will chime in with bullshit about how the show is not as good anymore, which is definitely true, but no other show on that poll will last as long as The Simpsons has nor will it even be remotely on par with its comedic level. Compare Family Guy's current eighth season with The Simpson's fucking classic 1997 season and you've got a clear winner. Matt Groening was also actually capable of producing a second great show in addition (Futurama), unlike Seth MacFarlane imo (American Dad and The Cleveland Show were never funny).
Actually I don't give a shit what any of you think but since nobody posts on these forums anymore I figured it's time to post something.
BTW, KOTH was also great.
