That was a clue in today's NYT crossword today. Perhaps, "I am a New Yorker" is enough to let you guess the answer if you know the number of squares. But it's not. There are 7 squares, and there's a slightly complicated trick to the puzzle, which is explained here — along with the answer — at Rex Parker Does the NYT Crossword Puzzle."
I tried to find the remark in context. Who was — spoiler alert — she responding to? Did somebody say he got to work at 7 a.m.? It's rather unGoogleable right now, because this one crossword clue is hogging the first couple pages of hits.
