I wish more of you were in Canada so I could just push you to Space where you can actually watch the entire series to date online right now.

Anyway in short it's about a Book of Pure Evil that gives the owner whatever they want, monkey paw style. Todd and his gang fight the book as the tagline says with mixed results. The first thing you'll notice is that for a show based on a teenage in high school it's decidedly adult (content wise not maturity) not just the language but the gore. It's cartoonish and hilariously awesome. I've never laughed at a dude getting his giant talking chopped off before.

Promos

In addition to that last promo, there actually is a metal musical episode. Aired last week and I so hilarious I've been watching it over and over again. I haven't rewatched a music episode this many times since the third episode of Glee*. The fan favorite song is "Horny Like the Devil" this will ruin some minor aspects of the show but nothing big and it's still fun to watch unfold.

My only problem is who gave Jason Mewes old man moves? He's not that old. (also that episode also features a number called "Wolf Rape".

Where to watch:
