While we're on the subject of donkeys . . .
A man and his wife are on holiday in Mexico. While shopping in a small village, the wife asks her husband what time it is, and looking down at his wrist the man realizes he has left his watch in the motel room. After a few unsuccessful attempts to find an English speaking local, the couple finally find an elderly man sitting quietly on the street with his donkey.
"Excuse me," the husband says, "Could you tell us the time?" "Absolutely", replies the elderly man, and reaches down and grabs the donkey's balls. "It is 3:00," says the peasant. "Thank you," replies the wife in a surprised voice.
After doing some shopping and grabbing a bite to eat, the couple return to the old man for the time. Again the elderly man grabs the donkey by the balls and says: "It is now 4:45." "That's amazing," says the husband. "How can you can tell the time like that?"
"Sit here where I am," says the peasant. "Now, do you see the donkey's balls?" "Of course," the man replies. "Now reach down and take them into your hand." Hesitantly, the husband does as he is instructed."Now, slowly lift them," he continues. Again the husband does as instructed. "Now look underneath the donkeys balls, and between his two front legs." The husband does as he's told. "Now," the old man says, "Can you see the clock on the wall of that building over there?"
