The Evolution of a Man Raised in a family of mostly men, Casey is a gritty, grimy, grunting sheet metal worker whose idea of funny is passing gas at the dinner table. Fiancée Lucy, who is not so easily amused, loves Casey dearly, but insists she's not marrying a man who hasn't evolved past a Neanderthal. Casey is a great dad and has been a good partner, but if he can't clean up his act, those wedding bells may never ring.
