Yesterday, my flight from Caracas to Miami was preparing to taxi and the pilot did his PA thing (time, weather, thank you for flying American, etc.).
There was brief silence and then, on the PA:
"We have Clearance, Clarence"
"Roger, Roger"
"Give me a Vector, Victor"
(it wasn't the pilot, but the soundtrack from Airplane)
The flight attendants were cracking up (as was I), although 95% of the passengers didn't get it or weren't paying attention.
Improved my flight, but I doubt they'd try it on a domestic flight.
