I'm a regular crossword puzzle do-er, and am always learning more about the vocab and nuances and well, stock answers, of the medium. There are a few standard clues that tend to come up over and over again, "Peter Fonda 1997 role" (ULEE), "Sewing case" (ETUI), and what's probably the most occuring crossword fill of all time, ORE and its partner OREO. Look at all those vowels and the wonderful R.
So, of course, I get it, and then I'm craving Oreos for the next three days. (The only thing worse is DONUT.)
