In this film from the late 1970s/early 1980s, there are a collection of comedy sketches.
In the first, there are men dressed as sperm in diapers. Most are laying around lazily, while one is constantly working out to be the first to the egg.
At the end of the skit the lead sperm yells for everyone to go back because it is a blow job.
(Note: this sketch does not have Woody Allen in it.)
In another sketch, there is a drunk guy walking down the hall in a hotel. A guy has asked his wife to go out and get his shoes that were polished for him. When she goes out to get them, she is naked and the door closes behind her. As the drunk approaches, she uses the shoes to cover her private parts. The drunk looks her over and says something like, "That a boy, shorty, give her all you got."
I thought it was Kentucky Fried Movie, but it doesn't appear to be.
