A raunchy, playfully obscene British sex comedy that mingles the adult animation absurdity of Monty Python's Flying Circus and the libidinous madness of American Pie, chronicles the rise and fall of a man's erection, a rib-tickling quest for the holy grail of sex, and one man's triumph over his own dorky, self-repressing nature and the "well-endowed" forces of nature around him.
