A local laboratory employed a licensed boat captain to man its research vessel. Reportedly, the captain couldn't swim. A newcomer, learning of this, approached him about it.
"Is it true?" the newcomer asked incredulously. "You, a boat captain, can't swim?"
"No I can't," the captain replied. "Can pilots fly?"
