Chatterbox (1977 film)

The film stars Candice Rialson as a hairdresser who discovers her vagina has the power of speech after it derisively comments on a lover's performance.

Her talking vagina has a mind of its own, which includes a desire to sing; they wind up exploited by her psychiatrist, who launches her on a career in show business.

According to Michael Medved in The Golden Turkey Awards, the talking vagina precipitates many developments in her life: Escapades include a sojourn in jail with a basketball team and sessions with a psychiatrist to help Virginia overcome her (its?)

At a show hosted by Professor Irwin Corey, Virginia sings in public for the first time, becoming a star after crooning a disco tune.

"A lesbian tries to rape her, she’s put naked on a board in front of a room of scientists while her vagina sings (and she’s clearly not having a good time), she’s forced to perform a big song and dance number where her clothes get ripped off, her love interest is an insecure drip...if I’m not mistaken she’s also gangbanged."
