So Wilbur had a horse that could talk. And "My Mother the Car" didn't stop yammering for a minute. But have your ever heard of a talking vagina? One that sings (it would dance, except that it's planted firmly in place).

Surprisingly enough, this humorous premise holds up well for all 74 minutes of Chatterbox, the ultimate paradox of the Deep Throat legend. In that classic adult film, Linda Lovelace had her clitoris stuck in her throat. Here, the lovely Candice Rialson, in the lead as Penelope, has a vagina with a mind of its own, in addition to a well-defined New York accent.

This little movie that failed at the box office in the late 1970's should do very well in the home theatre. Fun for all, it's the kind of film that spices up dull parties and can be a bit of a turn on as well, thanks to the presence of Rialson. She's a comely blonde with a lithesome body and a cute naivete that makes her adventures more charming.

When Penelope discovers that her genitals can sing, her social and sexual life begins to deteriorate. The vagina, named Virginia, is a wise-cracking, horny thing that thrives to have sex all night and be a movie and singing star by day. After Virginia quips, "Let me talk to him, I'll tell him what a loser he is," Penelope's boyfriend leaves her in a fit of rage. It seems that he was unsatisfactory in bed, according to the talking trap.

Penelope visits her psychologist, who is amazed at her new talent. "Let's keep things straight doctor," Virginia says. "I'm the wonder. She's just tits and ass."

Doctor Pearl exploits Penelope, turning her new asset into a show biz star. He becomes "Dr. Pearl, Theatrical Bookings." She debuts at a nightclub where the vagina sings "Swanee River" and it's on to stardom from there. Appearances begin on television, on magazine covers, at baseball games (singing "The Star Spangled Banner"), and she makes an album and stars in a movie musical. But all this time, Penelope gets increasingly more depressed, with big success, but no love in her life.

For the most part, Chatterbox is a pleasing sort of throw-away film —guaranteed to make you laugh. Virginia's wry sense of humor balances the skeletal plot well. When negotiating merchandising rights, someone asks Penelope if Virginia has star quality. Virginia interrupts, "Does Howdy Doody have wooden balls?"

In addition, Virginia is so horny that she forces Penelope to walk the streets of New York like a hooker looking for sex, and Virginia's "sense of humor" gets Penelope in trouble with an entire high school basketball team. At a restaurant, the rambunctious sex organ asks a waitress, "Do you serve a box lunch?" and flatly states, "I'll have a tongue sandwich, very lean." I'm sure you get the idea.

Now there's very little sex to speak of in Chatterbox, but plenty of nudity. Rialson is a feast for the eyes, so that should not disappoint anyone. It's more like a dirty joke movie with plenty of cameos (mostly people that you might find on "Tattletales" or the "Merv Griffin Show") by people like Rip Taylor and Herve Villechaize.

Chatterbox classifies as the softest of this month's softcore video releases, but one worth catching for its raw humor and undeniable charm.
