I didn't watch it last night. I am a fan, but have been uncomfortable a couple of times so I turned it off. I didn't care for the one where they crapped out their mouths, and this last one probably would have made me change the channel. That is why I have a remote, to change the channel when something is on that I don't like. I do enjoy the saddam ones where he is the devil's boyfriend. I also like their dreidel song on one of the holiday shows. The picture you posted made me laugh again when I started remembering the episode....funny!
BTW, the recall election vote for kindergarten president that ended with the teacher telling off Rosie O'donnell is one of my all time favorites.
The one where they crapped out of their mouths was so funny because it was making fun of some of the liberal stuff that is spewed out of liberals' mouths.
The analogy was dead-on.
Comedy's an art, not a science, and it's a variable one. It's OK to not love every episode equally :~D and it's healthy to have a line ~somewhere~ you don't want to cross :~D
