Facebook fan Mark Surks was watching new hit tv show "Blue Bloods" starring Tom Selleck and Mark Wahlberg when he noticed a familiar book cover in one scene.
As a New York subway train pulls into a station you can clearly see a passenger engrossed in Wex's New York Times bestseller.
Mark paused his TIVO and snapped this shot.
We would like to confirm for the record that this is not an example of product placement. No money was handed over to ensure Kvetch stays in print.
Thanks to Mark for this picture and his eagle eyes.
