A couple of things come to mind!
1. The flight attendent calling up and asking us to turn on the seat belts because somone was doing yoga in the galley, and refused to leave.
2. I have a small grasp of French - when we were deplaning after a redeye, a little old lady walked by and was saying "jamais (my airline) jamais (my airline)" I thought she was saying "J'aime (my airline)" so I put on my biggest smile and said "Merci beaucoup madame, merci beaucoup"... The in charge flight attendant just about fell over laughing. So J'aime means I like/love... Jamais means never again. So this lady comes up and is saying never again will I fly with you - and I smiled super big and thanked her very much.
