Paul Slava sent me this gem via Mod Cinema, who wrote a far better description than I could:
a scene from the 1972 film "Four Dimensions of Greta." Tacky British sleaze at its most glorious and dubious - featuring possibly the worst German accent ever committed to film, enough pubic hair to stuff two sofas, and some of the worst acting and limb contortions ever seen. Greta was Britain's very first 3D feature film and was directed by Pete Walker ("House of Whipcord" and "Cool It, Carol!")
Go on, admit it, you recognize him - Robert Scorpio!
