Today's puzzle reminds me of the great Monty Python sketch set in a courtroom, where one of the witnesses, a detective, breaks into song about his choice of occupation, had he not gone into police work: "If I were not in the C.I.D., something else I'd like to be. If I were not in the C.I.D., a window cleaner me! With a scrub, scrub, here..."
You get the point.
Mr. Pink selects five well known people and reinterprets their last name as a verb describing work in another profession. I'm impressed that all five have last names consisting of five letters ending in -S, such that you can just say their name, and it works. Thus, ROSAPARKS cars, or SEANCOMBS hair. It's a nice selection of celebrities as well: two women, three African American, and only two old white men. I've always been fond of JEREMYIRONS for his portrayal of Claus von Bülow in Reversal of Fortune.
My error came today when I entered HOORAy instead of HOORAH and didn't check my crossing. It's almost as bad as guessing at "eta" vs "etd" or "alii" vs "alia." Or "esto" vs "esta." There's a lot of this sort of thing one comes across when one does enough crosswords. (My older daughter feels one shouldn't use the impersonal pronoun anymore. One disagrees.)
I very much approve of ABSCOND and FOMENTS. Nice words. I have very little to complain about in this puzzle, with the exception of 10D: Responses to mumbles (EHS). I just don't think you can make that plural. Otherwise, nice work!
