What's Up Nurse! (1978) ENF Funny
 

The ENF is brief, but enough to be allowed I hope. I made this clip myself, probably the only one from this movie.

Its kind of funny, some guy is walking along trying to catch butterflies or something while on the other side of a hill a bunch of naked girls are playing catch with beach balls. A beach ball gets away and the guy has it in his hand as one of the naked girls comes over the hill to get it. Reminds me of the old Benny Hill show kind of clips but its different. Watch the clip to see how it turns out, not great ENF, but the girls are worth the download.

..and so much sexier with a proper muff.
