A battle of wits and wills ensues between the boys and their angry mom, who wants to find out who ruined her expensive new red dress -- found partially burned and soaking in the toilet. It's Hal and Lois's wedding anniversary (hence the dress); and while the boys fend off their mother, with the long-distance assistance of Francis, a lonely and increasingly sozzled Hal bonds with the staff of the restaurant where he booked a table for the big night. Lois finally achieves an epiphany on the phone with Francis, who convinces her to for once "let something go." After she leaves for the restaurant, with the boys in tow, Hal arrives home to an empty house -- and we learn the truth about what happened to the red dress.
