" Grammar turns up in the strangest places, and so often in profanity, as we have seen. Did you ever notice that when son of a bitch is used as a slur, the accent is on the bitch, but that when it is used in joy, the accent can be on the son? Son of a bitch, that was my lucky day! Here, too, the original meaning is obscured, and beyond the degree in “sum-bitch” where bitch remains vibrant. "
