When Tom married Susan he thought he was only getting a new wife. He never even considered that he would be getting a brand-new family as well. Included in this new family are mother Sandy, the rule-maker of the house, and father Bill, once an only child, who could be the person Tom can relate to the most. There's also Susan's competitive sister Mary and her husband Chris, who considers himself Bill and Sandy's favorite son-in-law and finds Tom as somewhat of a threat. And finally there's Susan's brother Lewis, a shy and awkward young man who has made a career of collecting bugs. Other family members who occasionally drop by include Uncle Dave, the big-shot of the family, and Lisa, the youngest daughter who wants to backpack around Europe and become an art major.
