I'd just knock on the door, kid answers and I'd be like "Hey kid, is your Mum home ? Tell her, her friend Anthony from the net is here." Then hubby will be like "Oh yeah ? Why not join us for dinner"
The movie lightly visits it to keep to the theme, but yeah, super boring.
The 1964 classic was written by Nat Perrin, who also wrote some gags for Three Stooges. MUCH better than the shitty movies around now.
