Teenage Pajama Party(1977)

Teenage Pajama Party wastes no time as the opening credits roll while a variety of "teens" stroll through their inner city neighborhood and file into young Kim's (Candy Love) apartment for a slumber party. No sooner than the parents shut the door for their night out, the girls disrobe to a ripped off instrumental version of David Bowie's Fame. After a brief period of dancing they don their pajamas and gather around the telephone to listen to an obscene caller, an uncredited fat slob who masturbates while reciting a violent fantasy to one of the girls.
