Getting To Know The IN Crowd

Play associated audio

On-air challenge: Every answer to the given clue is a made-up, two-word phrase in which you add IN to the front of the first word to get the second word. For example: shoe insert; sole insole

Last week's challenge: This challenge comes from listener Ed Pegg Jr., who runs the website Mathpuzzle.com. The word "sort" has an unusual property: The first letter, S, is found inside the word "first." The second letter, O, is found inside "second." The third letter, R, is found inside "third," and the fourth letter, T, is found inside "fourth." Think of a familiar three-word phrase in 10 letters that has the same property, in which every letter in the phrase is found inside its corresponding ordinal. Here's a hint: It's something most people have, lose and regain. What is it?

Answer: Set of teeth

Winner: Daniel Heist from Brookline, Mass.

Next week's challenge: This challenge comes from listener Dan Pitt of Palo Alto, Calif. Take the name of a well-known American businessman — first and last names. Put the last name first. Insert an M between the two names. The result names a food item. What is it?
