Last time I had a heart-to-heart with him, it seemed he hadn't any taste for just black slacks in particular, as this is what I usually wear, you see. As for jeans, why, I haven't the foggiest. For your sake, I hope not. He may not mind them though. It's probably best just to hum at him adoringly. Preferably the star spangled banner--he's quite a patriot, you see.
