I agree csaddict. It was funny, like I think all SP episodes are funny, but IMHO it doesn't rank up there with Scott Tenorman, The J Lo/Affleck episode, and most recently the Christian Rock one.
I think it's probably because I have never seen any anime and really just don't have an interest in it. Like someone else said, I can appreciate the parody, the poorly-translated japanese music and the overdone cartoon characters, but the subject matter just wasn't that interesting to me.
I'm sure if I was younger and/or was a big anime fan I'd think this was one of the best ever. But...
