South Park and Futurama. We watch South Park religiously because it is the best comedy on TV- hand down. Yes, Seth McFarlane you heard Gfest correctly.
We still watch the reruns of Futurama for many of the same reasons and anxiously await the new series to start next month after a seven year absence.
Thanks to MooseCake at deviantART put together these awesome Futurama characters in South Park style.
McDux0r's over at YouTube put together this 30 second video of Futurama characters in South Park style. That is very enjoyable as well.
