A conversation between two American pilots in Colombia:

Pilot 1: "Well, we've removed the last of the double stacked pallets of aid that is supposedly intended for use in Venezuela."

Pilot 2: "Yep. This giant military cargo plane is finally empty of all of its humanitarian contents.".

Pilot 1:. "it seems like wasteful to fly all of these empty military cargo aircraft back to the states in this empty condition."

Pilot 2:. "I completely agree... If only there were some high-value commodity that Americans want, which was almost exclusively produced in Colombia. It would be exceedingly convenient to return cargo laden aircraft that were full of a hypothetical substance to our handlers..."

Poor 2: "Unfortunately, such a substance does not exist, because if it did then, we'd probably fill up each and every plane in service to the American public. But, there's nothing for it. A pity...."

Pilot 2: "Yep."

<Both pilots aggressively pick at their nostrils.>
