Smart Smuggling

Woo On rode a cycle carrying two big bags crossing the Mexican border whilst the customs officer questioned about him.


"What is the stuff inside the bag?"


"Sand"' Woo On replied.


"I have to inspect!" the officer doubted and raised the instruction to inspect.


After the thorough inspection, the officer found nothing inside the bag and had to release Woo On to pass the border.


The next day, Woo On appeared with the same two bags of sand and officer stopped him for check, failed to find anything and let him go....finally!


Woo On did that the same everyday for almost a year, and the officer had failed to find anything at all!


Till one day, Woo On did not show up anymore....well, later on the officer met Woo An in a little bar drinking beer!


"Hey, fellow, what the hell you were trying to smuggling in the past year. I really did not find anything in the bags? I would like to know, as here only you and me here only! What was in the bag? And what did you smuggling!?


Woo On smiled gracefully and swollowed another mouthful of beer, said "Bicycles!"
