"There is a drinking game associated with Withnail & I. The game consists of keeping up, drink for drink, with each alcoholic substance consumed by Withnail over the course of the film. All told, Withnail is shown drinking roughly nine and a half glasses of red wine, half a pint of cider, one shot of XXXX (vinegar or overproof rum are common substitutes), two and a half shots of gin, six glasses of sherry, thirteen glasses of whisky and half a pint of ale. It may be presumed that this quantity of alcohol, if consumed during the course of the film, would prove fatal."
