Last week's challenge from listener Steve Baggish of Littleton, Mass.: Think of a well-known actor, three letters in the first name, seven letters in the last. One of the letters is an "S." Change the "S" to a "K" and rearrange the result, and you'll name a well-known fictional character. Who is it?
Answer: Tinkerbell, which comes from the name of the actor Ben Stiller.
Winner: Lynette Hendricks of Dallas
Next week's challenge from listener David Rosen, a member of the National Puzzlers' League: The name of something that you might see your doctor about is a two-word phrase. Three letters in each word. When these six letters are written without a space, a three-letter word can be removed from inside, and the remaining three letters in order also form a word. What's interesting is that the four three-letter words — the two in the original phrase, the one that was removed, and the one that remains — all rhyme. What is the original phrase?
