Jack, "Jig" or "jigaboo" is a derogatory American term for a black person. And it just happens that "Jig dolls" in the UK have black faces, but of course it has nothing to do with racism. And you know damn well that people bring up stuff like this for thinly-veiled racist purposes.
So, yeah, people take offense at it. Get over it. I suppose we could ban it altogether, but we're trying to take a middle path. In fact, I'll stretch it just a little more to keep Jack and Jeri happy.
