Life’s good for deliveryman Doug Heffernan, until his newly widowed father-in-law, Arthur, moves in with him and his wife Carrie. Doug is no longer the king of his domain, and instead of having a big screen television in his recently renovated basement, he now has a crazy old man.
Doug and Carrie run into Doug's ex-girlfriend Trish at an art gallery. Doug explains to his wife that Trish took their breakup pretty hard. So, against her husband's wishes, Carrie asks Trish out to lunch. At the restaurant, Carrie quickly realizes why Doug broke up with the woman in the first place – she's annoying and needy. Ready to break off their new friendship, Carrie's tune changes when she discovers Trish's employee discount at Saks Fifth Avenue. Meanwhile, Spence agrees to go out with a guy, even though he's not gay, just to boost his morale.
