I actually enjoyed the newer seasons as well. That midget fighting episode is probably one of my favorites.
Yeah Season 8 really was the last great season but since then they always have that one great episode
Season 9 - Trapped in the Closet
Season 10 - ManBearPig
Season 11 - Le Petit Tourette
Season 12 - The China Probrem
Season 13 - (was great from start to finish)
Season 14 - It's a Jersey Thing
