I remember watching it on Cinemax in the late 1980’s. It was a crappy German sex comedy (dubbed) about a guy who had to sleep with a variety of women in order to get an inheritance from a rich uncle. There was one scene near the end where he and a girl are fooling around in a department store after hours. They’re discovered by a near-sighted security guard and the girl avoids getting caught by pretending to be a mannikin. Any ideas?
Sounds startlingly similar to a Uwe Boll film I’ve seen called The First Semester. Alas, it’s from 1997 so it’s probably not the one you’re thinking of.
I believe the English title of your movie is I Like the Girls Who Do.
Amazing! That’s it.
