An e-mail:

I’m sure you didn’t mean to use “roll” for “role,” but it does raise an interesting “Baba Wawa”-type question: If John Ashcroft could be a roll, what kind of roll would he be? By caricature, maybe “whole-wheat,” “sourdough” or even “kaiser,” but I think that he would prefer to be a hearty “potato” roll.

I’ll never make that typo again, for sure…
