A tourist goes to Mexico with a tourist group, but finds himself separated from them. The only thing he knows is that he's supposed to meet with his group at the church in the middle of town at 6:30pm to go back to the hotel. Like an idiot, he didn't bring a watch with him. So he walks up to a man sitting on the edge of the road with a donkey standing next to him
"Excuse me...uh...habla ingles?"
"Oh good. Do you know what time it is?"
The man sitting in the road grabs the donkey's balls and lifts them, "well sir, it's 5:15pm"
The tourist walks away dumbfounded and disturbed, but strangely impressed. He wanders around the town a bit longer but doesn't go too far so as not to get lost and makes his way back over to the man in the street. "Excuse me again. Can I get the time?"
The man grabs the donkey's balls, lifts them, "it's 6:20."
"I'm sorry, but how is it you can tell time by fondling that donkey's junk?"
"Well you grab the donkey's balls like THIS...you lift them like THIS...and you see that clock over there?"
