A Mexican teen came up to the Mexican border riding his bicycle carrying two large bags on his shoulders. The officer stops him and says, “What’s in the bags?”
“Sand,” he answers.
The officer says, “We’ll just see about that." He takes the bags and rips them apart; he empties them out and finds nothing in them but sand. He detains the teen overnight and has the sand analyzed, only to discover that there is nothing but pure sand in the bags. The guard releases him, puts the sand into new bags, hefts them onto the lad’s shoulders, and lets him cross the border.
A day later, the same thing happens. The officer asks, “What have you got?”
“Sand,” says the youngster.
The officer does a thorough examination and discovers that the bags contain nothing but sand. He gives the sand back to him, and the young man crosses the border on his bicycle.
This sequence of events is repeated every day for three years. One day, the teen doesn't show. Days pass and the officer never sees him. A month later, a messenger comes and hands the officer an invitation for a house warming.
When he gets to the address, he sees it's a large villa with a pool, and many guests celebrating. Inside he finds the teen, holding a glass of wine and enjoying his guests.
“Hey, Buddy,” says the officer , “It’s driving me crazy. How are you so rich when all you were carrying across the border was sand? Just between you and me, what were you smuggling?”
The youngster flashes a smile and says: "Bicycles.”
