Al and Brendan get more than they bargained for when they agree to take care of a neighbor's St. Bernard ... way more, especially after the dog's masters decide to move away and leave the dog in the Lamberts' care. Everyone becomes even more miserable when Carol falls in love with the slobbering mutt.

Karen realizes a dream when she takes a modeling job in Chicago, but she has to deal with her overbearing mother. Carol tags along and interferes with the photo shoot, angering Karen. However, one of the other models takes Karen aside and shares her dream ... just to be a kid. Meanwhile, Dana - and then the others, one by one - come down with the flu. They all quickly make Frank their butler, which (along with Mark sharing how often he has to vomit) drives family patriarch crazy.
