someone know this C or D movie?

ok some years ago (10 or more i think) i saw this horror(?) movie in tv where 2 guys were running an vegetarian restaurant by day and killing people by night to make an godess(?) from the parts while mixing the "leftovers" in the vegetarian meals.
I think they got orders from their uncle(?) who was a brain in a glass and could talk (he wanted a new body AFAIR) (im not shure about this part)
in the end they managed to summon the goddess which had an big mouth in her belly (or a "big gaping vagina in size of a hallway"-with-teeth
i want to rewatch this movie 
pretty please? O_O

I recall that, I think it's called "Take another hit."

hm its not on imdb under this title (and google wont help either)

Wow.  Just, wow.

I'd like to know the title of a french film. I only saw the last 30 minutes where the family had gone to recover leaving the father at home with a rat. They mother phones her husband to say the rat is the problem and he should dispose of it. He microwaves it and eats it. The family come home and he has turned into a giant rat and starts attacking the mother. The daughter, who is in a wheelchair, starts crawling around with he arms, grabs a knife and kills her giant rat father.

Anyone know?
