PA left on and needing hot woman

This classic joke, with variations, can be found in almost every book with airline humor. And it must have happened somewhere, somehow...
During a particularly rough flight, the airliner pilot addresses his passengers:"The turbulence we passed through was rough, but we have passed that now. The rest of the flight is expected to be smooth. "The pilot was unaware that his PA switch was stuck on, and leaned over to the co-pilot and said:"Boy, was that rough! What I need now is a hot woman and a cold beer."
A flight attendant in the rear of the aircraft heard this, and ran forward to warn the pilot.
As she neared the cockpit, an elderly woman passenger stopped her saying:"Don't forget the beer!
