Putting the Cult back in Culture

I think I've finally stumbled on my evergreen hook, the thing to whip out any time there's 3 minutes left in class and I'm not sure what to do...

It's a variation on the "I'm going to the moon" word game, where you make a list of words that all follow a rule; the trick to keep it fresh is that the rules change all the time...

So, I'm bringing a SHOE and a BROOM might indicate a rule about having double vowels, or about starting with double consonants...

Eventually, it might open some opportunities for discussing logic, degrees of freedom, and a couple of other math topics. Mostly, it's meant to be fun, and thinky.
