A few weeks back, David posted a bonus entry in which he launched an inquiry into the origins of Clay Davis' signature pronouncement—the now ubiquitous "sheee-it." (Three e's, one i, right Gus?) I had always assumed that David Simon, great lover of inside jokes that he is, had back in his Sun days reported on some real-life state senator who had a penchant for drawing out the vowels of his expletives. But an astute reader had informed David that Isiah Whitlock Jr., who played Davis, had actually uttered his first sheee-it not on The Wire but in Spike Lee's 2002 film The 25th Hour. This ur-sheee-it suggested it was not Simon's invention. So, whose was it?
I endeavored to put the question to Whitlock himself, which is how he ended up on my voicemail. By the time we connected, I knew I wouldn't be the first to ask, but I couldn't resist hearing the answer from the horse's mouth. Here, by way of valediction, is the story as Whitlock graciously told it to me.
He's been saying sheee-it for years. He picked up the habit, he said, from an uncle who apparently deployed the word in much the same way Clay Davis did. Whitlock offered an example: "How'd you enjoy your dinner?" someone might ask his uncle. To which he would respond, "Sheee-it, I tore them pork chops up."
So, we have Whitlock's uncle to thank for the inflection, but it was Spike Lee who gave sheee-it its big break. Lee, having heard Whitlock toss off a sheee-it or two in conversation, encouraged him to use it in The 25th Hour, in which Whitlock played DEA agent Amos Flood (and later in She Hate Me, in which he reprised the role). From there, someone on The Wire writing staff seems to have picked up on sheee-it's unique power. Whitlock says that when he got his first Wire script, it was already written into the part, extra e's and everything.
