Although BS promised it some time ago, there wasn't a dead mule in the prologue! RJ said that he wanted to include one in the prologue of AMoL, because it's typical for southern USA literature. Didn't notice it myself, when I read the prologue, but now that I'm aware of it, it's somehow a pity that RJ's wish wasn't fulfilled, because BS apparently forgot about it.

On the other hand, BS has yet two more prologues to include a dead mule..
