A package of baby diapers yielded an unlikely load in Mexico on Friday, according to the defense ministry: nearly half a  million dollars in cash.

Soldiers conducting a routine check “found in a tractor-trailer a packet of diapers containing 490,300 dollars,” the ministry said in a statement.

It said that the cash was likely a stash of narco-dollars destined for money-laundering, as the truck had come from Culiacan, the capital of Sinaloa state in Mexico’s northwest, a region known for trafficking by major drug cartels.The driver of the truck was arrested.

Now that’s a diaper I would have liked to change!
