Currently, there's 268 voters for this episode, and 195 give it a "10", 30 "9's", 23 "8's", the remaining seven stars are single digits...if you watch this episode, you'll see how suspicious this is!
This episode without spoilers: Women with robot voices that look like Freddy Mercury when he had the porn star moustache, a person with a garbage can over his head, zombies that click their teeth fast, a dairy cow that pops in wherever David is, a nightmare restaurant, an albino monk, and the non-sequitur scene flash hopping in and out of David's scrambled brain.
I'm convinced that the people responsible have a great laugh, week after week, when they see how highly rated this insanity show continues to be, and especially hearty laughs at the remarks by the pretentious that only the highly intelligent can understand it, and they'll not waste their time to explain it.
The beginning of this episode touches on the phenomenon of "mass hysteria", and the like. I think they are referring to all the "10" votes! lol
For the record, I enjoyed season 1 even as odd as that was, season 2 is complete nonsense.
