Early 80's comedy. There's a scene where some people are about to do some sort of "science experiment" (One or two guys had on lab coats as I remember), and it involved girls getting naked. Synth/80's new wave music was playing and there was a close-up shot of a girl pulling down her underwear. Pretty sure it aired on HBO in the early 80s.
maybe DR ALIEN??
That couldn't be it, as that movie shows a release date of 1989... the one I'm thinking of would have been no later than 1985.
Try the film Zapped(1982) starring Scott Baio and Willie Aames. This may be your movie.
Or MY SCIENCE PROJECT (1985)

My Science Project shows a PG rating, so I'm pretty sure there isn't frontal female nudity in that one! Ha.
Zapped sounds more promising, but the "Parent's Guide" section on imdb doesn't seem to mention a scene like I remember.
Thanks for the suggestions, but I think this is still unsolved...
look up IMD 80's sex comedies A great list here ! Maybe you'll find it !
