Trouble Comes in Threes?

In my dream last night, one of my law school professors (some of you will be able to guess which one) said:

One Medici, I am fine. Two Medici and we are fine together. Three Medici and we are all banned.

Other than being historically inaccurate (the Medici mostly got along quite well with each other), it’s a nice line. I’m also pretty sure the professor in question didn’t actually say it, although I can now easily visualize him doing so. The rueful tone with which he said it in the dream — we’re fine people; it’s just that we can’t get together without it turning into a disruptive competition — really made the dream for me.
