Sam has to jet off across the country in search of replacement lobsters when a truckload he purchased for a very important wedding, is stolen. Danny and Mike play detectives to determine the motive and culprit behind the theft. Meanwhile, Delinda's childhood boyfriend Jay (guest star Geoff Stults), shows up with news that he's dying of cancer- and of his final wish to sleep with her. Elsewhere, Mary books Michael Buble (guest starring as himself) to sing for the wedding; but, has to wrangle him in when he refuses to sing, instead wanting to perform comedy or a mime act.
