At Panera the other day, I saw this poster:
I know what corn-fed beef is, it's when you feed the cow with corn. So what's vegetarian-fed turkey? Is it when you feed the turkeys with vegetarians? Maybe we could stretch it to mean that the vegetarians give the turkeys their food, but I don't know! What a horrible fate for a deceased vegetarian, to be fed to turkeys! Also, I don't think I'd want a sandwich made of such.
