Haven't listened to that episode yet. Will tonite when winding down. I love palindromes, and for whatever reason, my brain notices them in print. My most recent "discovery" was reward drawer. Shared that with a teacher friend who is also a palindrome fan. He liked it so much that he actually made it into a label for the drawer on his filing cabinet where he keeps goodies for his students. He tells me several have pointed out "Hey Mr. Copeland, did you know that spells the same thing forward and backward?" Teachers are always looking for tricks like that to stimulate students' minds.

Like I said, I haven't listened to that episode yet, so I hope reward drawer isn't already in there. But I was excited to find a 6-letter word which, when combined with its palindrome, made a sensible two-word phrase for which clues could be given and a logical meaning extracted. Of course, the frequency of palindromes drops dramatically as the number of letters increases. See this tabulation:  http://www.springerlink.com/content/l223x6kmu014x316/
