On the most recent DR archive at around 2:10:30, after Fred from Honolulu's call:
A Mystery Caller doing a funny voice asks the DR hosts if they are aware of the town of Montclair, in Essex County, New Jersey.
Follow up question from the Mystery Caller: Are they aware of some of the half-price pasta specials available in the town of Montclair, from Mondays to Wednesdays? Such as the tri-color tortellini?
I have my suspicions about the Mystery Caller's identity, but no firm proof.
