Funny Friday: Banter between Two Siblings

Brother: What day is it?

Sister: Friday, if it doesn’t rain.

Brother: What day will it be if it rains?

Sister: A rainy Friday.

I am not sure where I heard that, it could be a memory from my childhood because it sounds like the banter between one of my younger brothers and me. I hope it gives someone a laugh, I think people should laugh at least once a week.
