Yes, many of these funnies have become quite standard and boring now. They originally began with a PSA (of California) F/A many many years ago. On a recent Canadian North flight I was on, the F/A was coming around with hot meals (note: in Economy Class - on a 90 minute flight), she asked the guy in front if he wanted a meal. He looked at her, hesitated and then said 'no'. She smiled and said, "you sure now? I'm only serving it; I didn't cook it". Most probably not that original either (and she probably says it every flight), but it did make me laugh.
