Here are some of the weirdest I have heard
The Captain was giving us our routing and told us to look out for his Son's Alma Matter School on the right and sing the Fight Song along with him.
On an international flight on Lufthansa the Flight Attendant started to read the ingredients of the Inflight Meals and told us to have our pick.
On Southwest the Flight Attendant taught us how to open up the bags of peanuts and she counted the nuts with us . Then she told us about why Club Soda is better than Coke. Shall we say it got heated lol.
