Many of the answers in this crossword are one letter too long and won’t fit in the spaces provided. Each of these answers will either begin or end in the gray square immediately before or after it. When the puzzle is done, all the gray squares will have been used exactly once, and the letters in them (reading left to right, line by line) will spell out a quote by Chris Rock.
Heads up: if you're planning on solving this in Across Lite, you might want to set the printing feature to change the black squares to be something much lighter. Also, thanks to Joon Pahk for the PDF.
