I LOVE Guy and Guy's Big Bite. I have every ep on DVD and watch them. He's on every day now and I watch every day. I love him.
Amy, last years winner had a 6 week run and it bombed. She likely won't be back, but there's no way to know at this point. They do new shows all the time.
I like a very limited number of FN host, coincidentally the only ones I like are the men. There is not a female on the FN that I'll bother with. Not Rachael, not Paula, not Amber, not that "Cooking for Real" chick, not the Neelys (they are horrid IMO). I only like the men. Tyler, Bobby, Danny, Guy, and Michael. For whatever reason, it doesn't seem like the guys have to try too hard, unlike the women.
Interestingly enough, the fan vote which doesn't mean anything this year, is going toward Kelsey. If she hadn't screwed up and said "Culinary school" one time too many for Bob's taste, she'd likely still be there and Lisa would be gone.
