Feeling unspeakably guilty, Jack returns to the ship, only to learn that Jill has gone back home to The Bronx.At a restaurant on New Year's Eve, toting a picture of her and Jack's late mother, Jill comes across a group of former classmates who always made fun of her; these classmates, led by Monica (David Spade), pick up directly where they left off...until Jack, his wife and their kids show up.Jack's agency client, meanwhile, wants him to somehow get actor Al Pacino to appear in a Dunkin' Donuts commercial.Jack isn't sure how he's supposed to make that happen. She has no success until Jack poses as Jill and alters her profile, leading to more than 100 responses.Jill (also played by Sandler) never left the working-class neighborhood they grew up in; she recently inherited the Sadelstein home, having lived with their mother until her death one year ago.As always, Jack is irritated by the upcoming Thanksgiving visit of his sister.
Jack finally calls her out for making a fool of herself, of him, and of everybody else at the table.
Jill suspects that Jack invited her on the cruise just so Pacino would do the commercial; such is confirmed when she phones Jack, he answers as Jill, and then she hears Pacino in the background.
Pacino, still believing Jack to be Jill, spells out that he (Pacino) sees much more in her than just a pathetic half-wit...which is what Jack always took her for.
Jack's friends and colleagues throw him a birthday party, extending the invite to Jill.
Again Jill loudly disgraces herself, Jack, and the various celebrities in attendance.
