hmm... I don't quite see it the way you do....
What if.... is the big question. There are a lot of what ifs that can apply to doing that.
Mostly its, what if somehow, for some reason the donut'ee got hurt doing that, and decides to sue sue sue..... who's the looser then? That happens way to often these days.
I belive in having a good time, and god knows I've dome my share of spinning, but if you get caught.... oh well, its time to pay up....
I'm not trying to start a war here, just my take on the subject....
