Can I Do It... Til I Need Glasses?, 1sh 1977- Robin Williams first!

Can I Do It... Til I Need Glasses?, the 1977 I. Robert Levy sexploitation comedy skit-compilation ("It's the nuttiest, naughtiest, looniest, gooniest, funniest madcap comedy of the year!"; "from the same wonderful nuts who gave you 'If You Don't Stop It... You'll Go Blind!!!").  Note that Robin Williams' scenes did not make it into the original theatrical release. However, once he became famous for TV's "Mork & Mindy", his deleted scenes were edited into the film and it was re-released in 1979 with advertising promoting him as the top star.
