Put simply, This is Spinal Tap remains one of the laugh-out loud funniest, most engrossing, and most quotable comedies of all time. The trick? Roger Ebert once wrote of another great comedy, Dr. Strangelove, that “a man wearing a funny hat is not funny. But a man who doesn’t know he’s wearing a funny hat…”, and the same principle applies to Spinal Tap. The performances of the cast are so wonderfully clueless and deadpan that it is impossible not to simply piss oneself laughing at so many classic moments, but more than that, it is that these guys are actually kind of likeable – the boys that make up Spinal Tap are complete idiots, but they’re our idiots, and we get to laugh at them. What else do you need for a great comedy?
