This is a SERIOUS BBC documentary about tourettes syndrome that went on to become a cult-classic comedy, though you do feel guilty about laughing afterwards. This film follows around 16 year old John Davidson who suffers from full blown tourettes. Having self diagnosed myself as having a mild case of tourettes in my pre adolescent days i can completely empathize with poor John. Tourettes is basically overwhelming obsessive compulsions that are either vulgar and or odd little sounds shrieks etc.- as you will see if you watch the film. In John's case its yelling profanities at the top of his lungs at the oddest and most humorously entertaining times, yelping like a dog, spitting in peoples faces and blurting out every irrational and downright rude thought that enters his mind. My personal favourite is when he yells "mom your a slut" in the grocery store in front of an old lady. I found this HYSTERICAL...but at the same time i felt his pain, though not to the same extreme. This is great as both a documentary and for a good laugh. 10 out 10.
