On Letterman last night, Ricky Gervais explained why Jamie Oliver's Food Revolution is going to fail: because fat people love cake:
"His heart's in the right place, but you're right, he's got no chance... They know what they're doing. They know what's making them fat. It's all the pies. ... So if you go, all those pies are fattening, they're not gonna go, 'Really, I thought it was the jogging that makes you fat.' It's their choice... They know why they're fat and they like it."
