Recently I've watched one more time all the sixty episoded of southpark. There are some episodes I really like, for example 106-Death, 108-Damien, 203-Chickenlover, 311 - Starvin' Marvin in Space, 313- Hooked on Monkey Phonics and last two aired ones (411&411). My favourite is 301-Rainforest Schmainforest.
But, there are also some really weak episodes - for me the worst episode is 307: Cat Orgy. Just to refresh your memory: it's one of three episodes (Cat Orgy, Two Guys sitting in a Hot Tub, Jewbilee) where boys are separated. This one is about Cartman being babysited by Shelly. It's not funny, it's really boring and it is focused on one of lamest characters in the show - Shelly. I wish they got rid of her.
What are your least liked episodes?
