The outrageous sex comedy If You Don't Stop It... You'll Go Blind!!! (1975) features George Spencer, Patrick M. Wright, Garth Pillsbury, and Mr. Skin Hall-of-Famer Uschi Digard acting out a collection of classic dirty jokes in a series of vignettes. The action against which the title warns is one in which you may well find yourself engaging when you see Uschi go fully frontal. If you have to go blind, it’s not a bad sight to go out on.
