I think this would work best with a sunday funday or something like that. So im not sure how to word this properly, but I was watching Who's line is it anyway and I think it would be a good sunday funday to have the community give out who's line is it anyway questions and also answer them.

So it would be like
Things you can say to your GM but not your wife.

And then you can respond with "I think I can only go 20 minutes, but I can go 25 tonight"

or something like that. Im not sure if you can twist it into a sunday funday or something
