You will really love this conversation

While crossing the US-Mexican border on his bicycle, the man was stopped
by a guard who pointed to twosacks the man had on his shoulders.
"What's in the bags?"

"Sand,"said the cyclist.
"Get them off - we'll take a look," said the guard.

The Cyclist did as he was told, emptied the bags, and proving they contained
nothing but sand, reloaded the bags, put them on his shoulders and continued
across the border.

Two weeks later, the samething happened. Again the guard demanded to see the
two bags, whichagain contained nothing but sand. This went on every week for
six months, until one day the cyclist with the sand bags failed to appear. A
few days later, the gaurd happened to meet the cyclist downtown. "Say friend,
you sure had us crazy", said the gaurd.

"We knew you were smuggling something across the border. I won't say a
word - but what is it you were smuggling?"

"Bicycles!"
