Passengers on a small plane are waiting for the flight to leave. They're getting a little impatient, but the airport staff assures them the pilots will be there soon, and then the flight can take off.
Finally the entrance opens, and two men dressed in Pilots' uniforms walk up the aisle. Both are wearing dark glasses, one is using a guide dog, and the other is tapping his way along the aisle with a white cane.
Nervous laughter spreads through the cabin, but the men enter the cockpit, the door closes, and the engines start up. The passengers begin glancing nervously around, searching for some sign that this is just a little practical joke. None is forthcoming.
