From 2004:
I love parody and caricature, and it’s one of my medium-sized regrets that I have no gift for either (though I can do adequate impersonations of a few of my friends). Alas, I find it impossible to get inside another person’s prose style. I once tried to write a parody of a Jeeves novel in the style of Bright Lights, Big City. That was actually a pretty good idea, conceptually speaking, but I stalled out halfway through the fourth sentence, so it went unwritten, and the only thing I can remember about it now is that the very first word was, of course, “you.”
