Donkey Balls

Adam and his wife were taking a walk in the desert, just outside a city, to pass time. After having walked a little while, the couple wanted to check the time, out of curiosity, but Adam had forgotten his wristwatch back at the hotel.

They noticed a frail old man, sitting by his donkey in the hot sand, about a hundred meters away, and decided to ask him. "Excuse me sir, do you have the time?" The old man slowly nodded, turned towards his donkey, cupped the donkey's balls and lifted them slightly, about an inch. "It's 2:16, sir." The couple, astounded by what they had just seen, thanked the old man and went on their way, discussing about the odd event.

Time passed, and the couple still couldn't figure out how the old man had done it. They made their way back to him, and asked him again. "Excuse me sir, but do you have a watch?", Adam asked. "No, but I can tell you the time", the old man replied. He once again turned to his donkey, cupped the balls and lifted them, as if weighing them, and turned back. "It's currently 2:58." Once again, the couple walked off, thanking the man, and discussed what they'd just seen.

Nothing came of it, and they decided to go back one last time to the frail old man. "Excuse me," Adam said, "sorry to bother you again, but my wife and I were very curious as to how you could figure out the time of day simply by weighing your donkey's testicles." The old man chuckled, "You two aren't the first, but here sir, take a seat," as he got up from the hot sand. "Cup the balls, sir," he instructed. "Now lift them slightly, about an inch or so." "Now what?", Adam inquired. The old man went on. "Now look far off in the distance and tell me... do you see the big city clock?"
