I think it would be fun to take a picture of us that DOESN'T show our faces. Those of us with hats can sort of bow our heads so all you see is the hat. I have a couple of fun ideas for people who don't have hats - wrap your hair with a towel and lower your chin, so all we see is the towel. Or wear a drawstring hoodie with the hood up and drawstring fully engaged, so all we see is a nose sticking out. Or draw/cut out a silly face on a paper bag and put it over your head. Lol!! I'm giggling just thinking about it! I know the hat thing is supposed to be a play on "mad hatters" and "mad adders", but Ricky would be the first to say there are no rules about that, and no reason why we can't improvise and have fun with it.
Regarding the video - it takes quite some time for videos to process and upload. They are massive files. If you watch it live, plan on it being unavailable for at least an hour or so before you can go back and watch a replay.
