Indecorous Cake

Am I the only one addicted to that Food Network show "Challenge" where contestants furiously concoct sugary sculptures 3 foot plus in height? As if these wouldn't stand on their own as centerpieces, it's made so much better by the fact that the medium is...cake.

I wonder what happens when the show is over. People can't actually eat the centerpieces. Can they?
