One thought on “Knock, knock…uno?”

  It comes from the game ”crazy eights”, which is basically Uno, but with a regular deck of cards. Wen you have one card left in your hands, you have to knock twice on the table to avoid drawing 2 cards. But you get so paranoid that people won’t notice your knocks that you say it out loud at the same time ”KNOCK! KNOCK!”. Somehow it transcended to Uno and some people say ”KNOCK KNOCK UNO!”

  Thanks for that! – Y
