A mother gives her elementary school age son a glass of milk. He drinks it, and she tells him milk is a wonderful thing. Then he says he agrees that milk is a wonderful thing, and she’s a wonderful “milk” too: she’s a “Mother I’d Like to Kiss.” And then he kisses her on the cheek, and she smiles and blushes.
(This is obviously a joke on the term MILF, and as written would send the message to the people who buy the milk {Mom and Dad} without enlightening the kids to the MILF term, if there are any who don’t already know about it.)
