Well, let me ask you this, since I too will not watch it. When have they had an episode in which they have held HaShem up to ridicule and derision?
Well, they have often made fun of Jewish prophets, particularly Moses. They also made fun of the story of Job.
I consider the Jewish God the same as the Christian one, so I will say that they have made fun of Him many, many times. They show Him as some sort of weird, ugly, lizard creature. Jesus, too, is regularly made fun of.
None of this is ever intended to be malicious, as people think. It's just silly humor.
