Each Friday, I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.
Leave your answer in the comment section. I’ll approve responses later in the day to give people a chance to respond without seeing any spoilers.
This week’s riddle comes from NPR’s Sunday Puzzle and was initially submitted by Alan Hochbaum, of Duluth, GA.
