 Comedian Bill Cosby brings down the house to an audience in Ontario, Canada in a two-hour show where he pontificates on several subjects, such as drugs, drunkeness, and the follies of dentists, before launching into his primary subject matter, the hilariously pernicious antics of his family, from childbirth to college football to enduring a noisy four-year-old on a transcontinental flight to his son s bizarre hairdos to his wife s marginally restrained reaction to a childrens  squabble over the right to shower to his own father s nicknames to himself and his brother Russell.
