That's interesting, because I remember doing a cut&paste to make sure I got the wording right.
You may have, and Brian may have taken your comments to heart and changed the question. Certainly that wording invites more answers like "her TV show", "fashion design", "her huge ass" then the "doing" verbiage does.
"she made a sex tape"
I would fully expect that to come up and make the survey, but that's okay because, yes, she *is* famous for that, as opposed to "doing" "whatever isn't nailed down."
There's lots of ways to be thought-provoking or funny without resorting to prurience.
Seems like a decent rule of thumb is "the way this question is worded, can someone answer 'yermom' and it doesn't sound too terribly contrived? If so, rethink the wording."
