Mystery Hour Question
I was reading a book and saw the description 'on cloud nine.' I know it means that they were happy, but why nine and not any other number?

Answer: There was an international cloud atlas, which registered ten different types of cloud. The ninth type of cloud was the highest, so if you're at the highest level of happiness, you're on cloud nine.
