Exercising my brain, that is. Every week Will Shortz, editor of the NYTimes crossword puzzle, hosts the Sunday Puzzle on NPR’s Sunday Weekend Edition. He presents an on-air quiz and gives a challenge to listeners at home. Those who answer the puzzle correctly and submit it to NPR get the chance to go on-air with Will for the next week’s puzzle.

Here’s one example: Name something commonly found in an office. It is two words, with five letters in the first word and four letters in the last. Both words are the last names of famous singers. What is the office item, and who are the singers?

The challenges are sometimes easy, and sometimes brutally hard (like the one above). I share them with some of my colleagues at work so we can all exercise our brains. Check out the recent puzzles and see if you don’t go as mad as we do!
