The predilection for pure idiocy that runs through American culture has few finer exemplars than the Farrelly Brothers, Peter and Bobby, whose misshapen body of work includes "There's Something About Mary" and "Dumb & Dumber." But even the Farrellys genuflect in the presence of the Howards, Moe and Curly, and their co-conspirator Larry Fine, whose long-gone comedy act has inspired one of the Farrellys' better films and a movie in which excess -- the hallmark of everyone involved -- is decidedly a virtue.
