I saw it and didn't care for it but I wouldn't rank the episode very highly anyway. I'll see what they do next week.
I liked the episode, Satan episodes tend to be funny. And the Irwin bit was great, the whole idea of people like Hitler being offended by someone in an Irwin costume was funny, then to actually have it be Irwin and he gets kicked out for not wearing a costume was great. It's not like they had him sticking his thumb in animals' butts like the episode when he was still alive.
One of my least favorite episodes ever. The Irwin thing was nothing compared to the John Gasey, Ted Bundy, Jeffery Dahmer acting like the three stooges part. That was pretty sick.
