During the Pittsburgh Steelers-Denver Broncos tilt Sunday afternoon, the Play60 flag football kids trotted onto the field and a live mic captured a rather unusual sound right at the end of the presentation.

Whether one of these kids or Jim Nantz himself pulled the ol' Mike Ditka/Jim Tomsula or not is something we'll likely never know.

As for the game, it turned out to be anything other than a stinker, with plenty of intrigue down the stretch.
