Wanda's parents, Lloyd and Leora, visit the Mac household. Bernie and Wanda first think the visit will be good for the kids. But Lloyd and Leora start to give them more then they bargained for when hey start to criticize Bernie and Wanda's parenting skills. Bernie and Wanda decide to let the grandparents take care of the kids and leave for several hours. When they return, Bernie and Wanda tell Lloyd and Leora how they feel and decide the best thing is for the grandparents to leave. When Vanessa finds out, she is very upset because Leora did not tell her parents that a boy kissed her. Everyone makes up and decide to leave parenting to Bernie and Wanda.

Bernie's in-laws pay the family a visit and, as usual, Bernie and Wanda's father, Lloyd, bicker continuously. Wanda asks Bernie to go easy on Lloyd this time as her parents are having money problems and cannot buy a new Cadillac. But even when Bernie offers to buy the car, Lloyd refuses because it's not the top-of-the line model he wants. Meanwhile, we learn why the two men don't get along in a series of flashbacks, as Bernie takes us back to when he met Wanda and her father didn't approve of his daughter dating a comic delivery man who told jokes on the subway.
