BedDead and Breakfast (http://www.imdb.com/title/tt0350774/)
I got this movie for Christmas and watched it last night, and I have to say it's an amazing movie. It goes along the same lines as The Evil Dead and other humorous horror/comedy-style movies.
It's overly gory, involves chainsaws and hockey guns and a country/rap singer who is sort of a narrator who becomes a zombie (and still narrates).
I highly recommend it.
I must look in to this!
