Max (Matthau) and John (Lemmon) are back at each other's throats, but with John happily married to Ariel (Ann-Margaret), he's not much of an adversary. Enter Maria (Loren), who wants to turn the boys' favorite bait shop into an Italian restaurant. In a twist that should surprise no one, Max soon falls for the beautiful Maria, and she with him. Jokes are similar but more adolescent than in the first, and subplots involving John and Max's kids' wedding and Grandpa's (Meredith) romantic interests are forced. Suffers the standard sequel fate of not measuring up to the original.
