What's no. 1, or am I unintentionally beckoning you to violate it in making it vocal?

Actually the rule above is “non-cannon” [0]. In the official rules [1] number 1 is:

> Once you have their money, you never give it back.

There is no official rule 2 so the non-cannon one is as good as any and the unwritten rule [2]:

> When no appropriate rule applies, make one up

Means they probably would have been covered either way.
