Roger Corman's lawyers must have been on vacation when this little oddity hit drive-ins and theaters back in the early seventies. Please Don't Eat My Mother is a blatant rip-off of Corman's Little Shop of Horrors, with generous (make that copious) helpings of sex and nudity thrown in to make it commercially viable.
Henry (Kartalian) still lives with his mom, despite the fact that he appears to be in his mid to late thirties. He also has a serious voyeuristic streak and spends his lunch hours watching a young couple performing the naked nasty. Since the two of them get it on in a different location each day, it seems odd that Henry always knows where to find them.
The life of a peeping tom can be a solitary one, so to alleviate his loneliness Henry buys a strange looking plant. He talks to the plant and soon learns that it can talk back in a sexy feminine voice. The plant proves to be carnivorous, and soon graduates from flies to frogs then to dogs and cats. Before long she's chowing down on people, though she seems to prefer naked, well proportioned women.
This flick is a true gem from the drive-in era. Unlike a lot of films of this type, the acting is quite good, and some of the dialogue is hilarious. When the plant can't seem to understand why Henry is lonely for a real woman he tells her, "You're fiber vascular, you wouldn't understand." Upon learning of the delights of frog eating, the plant cries "Oh frog me, Henry, frog me!" with near orgasmic glee.
