Later issued on DVD as supporting program to "Doctor's Origins", we have the same premise of an unbelievably stupid teenage girl is relied upon for "The Consultation", with Tommy Pistol as an unscrupulous doctor. His victim is played for pity and borderline bathos by Adria Raye, introduced selling knives door to door.
She's working to finance a boob job, and having turned 18 goes to Pistol for the service, no parental approval or notification necessary.
He interviews her and discovering that she's still a virgin tells her a b.s. story about the dangers in leaving a hymen intact, and she stupidly believes him. So Tommy has sex with her to resolve the problem, ending with an empty promise of performing the plastic surgery later on.
