That Old Hose Bag Is My Mother

Evelyn buys Alan a new Sports car causing Charlie to claim that his brother has sold his soul to the Devil.  The next day, Evelyn extracts payment by insisting that Alan go on a blind, double date with her, her new beau and his daughter.  At the restaurant, Alan learns that his mother and boyfriend will not be able to join them because there was a mixup between his heart medication and Viagra and she didn't want to "waste it".  As a result, Alan is left to deal with the daughter, who is on a weekend pass from a rehab center and still has some loose screws.  Alan eventually gets her back to the beach house only to have her drive off in his new sports car and become the object of a televised high-speed car chase.
