What did the grape say when it got stepped on?

This little gem of a joke is a masterclass in wordplay, specifically a homophone pun. The setup builds an expectation that the grape will make a sound, perhaps a squeak or a squish, when it's stepped on. The humor then lands with the punchline, which cleverly substitutes the expected sound with a word that sounds exactly the same but has a completely different meaning: "wine."

The genius here lies in the direct link between grapes and the alcoholic beverage, wine. Grapes are, after all, the primary ingredient in winemaking, a process that traditionally involves pressing or "stepping on" the fruit (Review). This real-world context makes the pun incredibly satisfying, as it’s not just a random sound-alike but one deeply embedded in the grape's very purpose. The joke delights in the unexpected twist, taking a literal question about a sound and turning it into a witty reference to the grape's ultimate destiny.
