As stated previously, this is the Robin Williams reissue version which hit theaters after its initial run. The image quality is definitely better than prior home video versions; you can still tell it was shot for little money back in the '70s, but the candy-colored visual scheme looks great including one red-hued fantasty sequence that'll burn your TV tube. Extras include a full frame theatrical trailer (emphasizing Robin, of course), a smartass "extra" feature, and bonus trailers for The Obsessed One, Wacky Taxi, Power Play, Sole Survivor, The Farmer, Beyond the Door, and The Dead Pit.
If someone started grabbing random selections from a '70s edition of Playboy's Party Jokes and slapped them into a screenplay, you'd probably wind up with something exactly like Can I Do It Till I Need Glasses?, a lowbrow comedy skit film clearly modeled after the success of Laugh-In, Hee Haw and their dirtier offshoots like The Groove Tube. In fact, this was part of a two-film project from director I. Robert Levy, along with another, uh, similarly-themed film called If You Don't Stop It, You'll Go Blind. While the promise of two films promised endless masturbation jokes seems dubious, they proved successful enough to earn a long life on home video (from the long-deceased and beloved Media Home Entertainment). Potty humor and occasional full frontal nudity spark up the usual offerings of groaner punchlines and slide whistle music punctuations, but for most viewers the real selling point here is an early appearance by Robin Williams, who pops up in a couple of sketches originally left on the cutting room floor but reinstated after his smash appearances as Mork on Happy Days. Robin wasn't too pleased about this cash-in attempt claiming to be his "movie debut," though as anyone's suffered through Patch Adams or RV can attest, this is still a long, long way from the worst films in which he's appeared.
Obviously there's no way to offer anything resembling a plot synopsis, but for the record, the film stampedes through a number of jokey scenes, most lasting only a minute or two. Some of the targets include nudist camps, dentists, shipwreck survivors, Little Red Riding Hood, courtroom dramas, flashers, and even a male reproductive gag essentially swiped from Everything You Always Wanted to Know About Sex (But Were Afraid to Ask). Is it actually funny? Well, yeah, if you're in the mood for something really stupid and smutty with the attention span of an eight-year-old, which ain't always a bad thing. 
Break out a few beers and watch it with some buddies late at night on the weekend, and you can't go wrong. For the wrong, obscure celeb spotters should also watch for a few marginally familiar names like the comedy team Roger & Roger (doing a couple of Lone Ranger skits), TV regulars Jeff Doucette and Walter Olkewicz, Skatetown USA's Vic Dunlop, big-busted LA billboard goddess and gubernatorial candidate Angelyne, and purportedly a fleeting Uschi Digart as one of the showgirls.
