An American man visiting Mexico finds his wristwatch has stopped working. He’s got a flight to catch in a few hours, so he tries to ask a local the time but doesn’t know the language. Finally he meets an old Mexican man sitting next to a donkey who speaks English. “Excuse me, Señor, but do you know the time?” the American asks.
The old man reaches up and grabs the donkey’s balls. He twists them to the left, then he moves them to the right, then he lifts them up. “Sí, Señor, it’s 2:20,” he replies.
The American stands there for a moment, flabbergasted. Then he replies, “Gracias, Señor,” and walks away pondering what he just witnessed.
A short time passes and the American wants to see the old man’s trick again, so he asks him the time. The old man again grabs the donkey’s balls — he twists them left, then moves them right, then lifts them up. “It’s 2:45,” the old man replies.
“How in the hell are you doing that? How do you tell the time with donkey balls?” says the American.
The old man replies, “You see, Señor, I twist them left, I turn them right, then I lift them so I can see that clock over there.”
