Just thought of this. In fact this game could already exist. But whatever, I'll begin by writing a number then the next person has to say what that number represents. After they're finished they write down a new random number for the next person below them
Example:
A: 1
B: That's how many showers you've taken this month.
56
Get it? Good. Let's begin.
