I've been writing about Orlando attractions since the mid 90s and I think it must be Rule #1 in the CM handbook that, if at all possible, you should pick a foreign tourist as a volunteer.
The old Wild Bill's dinner show in Kissimmee (of blessed memory) had a hysterical skit where they did a sort of frontier Romeo and Juliet, picking two tourists, who didn't speak each other's language and didn't speak much English, to play the Romeo and Juliet parts. It was fall out of your seat funny.
Actually, having seen the Horror Make-Up show more times than I can count, I can attest to the fact that it is not always a Japanese woman. I've seen women from South America, too.
