Swearing, when judiciously employed, is brilliant. Sometimes, there’s simply no non-cuss word that will do, no mild alternative that can add the same perfect spice and flavor to a sentence. Arguably, one of the sweariest – and certainly one of the most quotable – films of all time is the Brit cult comedy Withnail and I. And some of its best swearing relates to the after-effects of booze. The titular Withnail, an out-of-work actor, spends three-quarters of the film drunk, and the rest of the time dealing with the fallout. His potty-mouthed evocations of alcohol-induced suffering are nothing short of poetic.
