“Sand,” answers the young man.
The guard is a bit suspicious and asks the young man to open the bags for inspection. The guard empties the bags, but finds nothing in them but sand. Then he has the sand analyzed, only to discover that there is noting but pure sand in the bags. So the young man is allowed to ride across the border with his sandbags.
A week later, the same young man presents himself at the border with his bags. The guard asks,” What have you got?” “Sand,” says the young man.
The guard does his thorough examination and discovers that the bags contain nothing but sand. He gives the sand back to the young man who then rides across the border on his bicycle with the sandbags.
This happens every week for three years. Finally, the young man no longer appears at the border crossing. Many months go by and the border guard meets the young man in an expensive cafe.
“Hey,” says the guard,” for three ears you were smuggling something through my crossing station. It’s driving me crazy. Just between you and me, what were you smuggling?” The young man drinks his coffee and says, “Bicycles.”
