So dairy farmers play it (it's true don't let anyone tell you otherwise). They line up a row of cows, and have someone close their eyes. Then they bring up one of the cows, have the person with their eyes closed kiss the cow, then put the cow back in line. Then the person opens their eyes and they have to guess which cow it was that they kissed.
Now sometimes a boy or a girl will have a boy or girl they're interested in play the game, but instead of bringing a cow to kiss them while their eyes are closed, they take the opportunity to kiss them!
