I listen to NPR's Sunday Morning show pretty much every Sunday. There is a segment called the Sunday Puzzle in which the host along with Will Shortz, the New York Times puzzle editor, have a caller give answers to different kinds of puzzles or riddles.
To get chosen to participate you have to submit a correct answer to the weekly puzzle then have your name drawn. I have never actually submitted an answer. This week the answer popped immediately in my head... at least what I think is the correct answer.
If I am correct and my name gets picked, I will get a call Thursday afternoon to record this Sunday's puzzler segment! Stay tuned.
