And speaking of grandmas, this season's theme is "Battle of the Ages," with contestants ranging from 24 to 65 who are broken up into under-30, 30-49 and 50+ groups. Bob and the powers that be swear that older players have just has much chance to win as their more sprightly competitors, but we all know that that is barely true.

This season also introduces two new trainers: tennis pro Anna Kournikova (who is no Jillian, I'll tell you that much) and "top" fitness expert Dolvett Quince (he's cool, I guess). If it were up to me, in their place would be Celebrity Fit Club's Harvey Walden and... a clone of Celebrity Fit Club's Harvey Walden. He's just really great, you guys.

Watch the weight come right off tonight on the two-hour Biggest Loser Season 12 premiere at 8 PM on NBC.
