While crossing the US-Mexican border on his bicycle, the man was stopped
by a guard who pointed to two sacks 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 same thing happened. Again the guard demanded to
see the two bags, which again 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?"
