The Film: Female Trouble (1974)

The Inappropriate: Teen runaway Dawn encounters the station-wagon-driving Earl while hitchhiking. They go back to his pig sty of a place and shag. Dawn ends up pregnant.

If that isn’t inappropriate enough, drag queen Divine played both Dawn and Earl in some very cleverly choreographed (not to mention stomach-churning) clinches. Divine shagging himself? There's a joke in there somewhere.

How They Make it Work: “Go fuck yourself,” yells Earl when Dawn demands money to help raise their baby (ah, there's that joke). Let’s just say it didn’t end amicably.
