A bit of a crazy story...from CNN:
"(CNN) -- The Mexican navy smelled something fishy and their intuition paid off. They found nearly a ton of cocaine hidden inside a shipment of frozen sharks.
The cargo, which was aboard the freight ship Dover Strait, had been loaded in Costa Rica, Mexican navy says.
The inspectors zeroed in on a shipment of sharks. Upon slitting one of the frozen fish open, they found black bags containing rectangular packets filled with cocaine."
