"Comment to an annoying blackjack dealer." This is the center clue to today's NYTimes crossword. The title of the puzzle is California, here I come.


Each major clue had the letters CA from California added. So, take the Isley Bros song "You make me wanna shout", and add CA to make it "You make me wanna cashout".
