I think we’ve played this game, or something similar, before:
List three people (or things, or a combination of both). The next player states what they have in common, and gives a new trio. Make 'em as easy or as hard as you want.
Well, since there’s no one on the planet, past or present, who’s ever lived in a place that has never been at war, I don’t think that’s a particularly helpful answer.
And “never been in Cliff Claven’s kitchen” is also a little too all-inclusive.
So, yeah, the thing I’m looking for is probably best, unless you come up with something of an equivalent level of specificity (as determined by me).
