Before there was the Slammers ( favorite professional baseball team!) there was the JackHammers. And the last manager in the JackHammers' glorious nine-year history was none other than New York Mets immortal (and fan favorite) Wally Backman.
The video shows Backman, um, encouraging his team? Anyway, the way Deadspin puts it, "this latest clip of Wally working his motivational charms is decidedly NSFW."
