The Young Ones (1982-1984)

Mostly sex references throughout seeral series, including some charachters still being virgins, and putting hands up a womans skirt, nothing is ever shown though, other than one character waking up next to an inflatable sex doll and the other next to a woman though nothing is shown to happen.

on the episode Time there is a skit of dallas at the beginning and in the images it very briefly shows a bare bum and several pairs of showgirls bare breasts however this is very short and not always easily noticed.
