Actually happened to me - I was the German speaker on the flight and doing the after landing PA started with the usual:
"Sehr geehrte Damen und Herren..."
Due to the fact that I was chewing on a gum a colleague gave me before landing it more came out like: "... Damen und Herzen..."
which would translate to "My ladies and darlings... " (rathern than ladies and gentlemen).
First and only time I ever chewed a gum while making a PA - got amuses smiles from the pax though - lucky I was sitting all the way in the back on that flight
