The usual bunch of the same old gags.....sorry, but I'm another of those sad gits who thinks professionalism is more important in flight crew than the ability to be amusing.
Personally, this would be totally groan inducing if I was a passenger, and totally embarrasing if I was a crew member. If I was the Captain I would be asking that such "hilarity" be kept to other announcements and the safety PAs be restricted to just that.
