The NL East rivalry between the Washington Nationals and the Philadelphia Phillies doesn’t involve just the players—it extends to the mascots as well.

Before Tuesday night’s game, Nationals star Bryce Harper pulled a prank on the Phillie Phanatic, stealing the keys to the mascot’s ATV. That got the fun started.

The Phillie Phanatic came back to his vehicle only to find that he had no way of starting it. He did what he could to try to find out who took the keys, even getting the police and security involved.

Eventually, the Phillie Phanatic got his keys back and went on his way. He has until Wednesday night to find a way to get back at Harper with a prank of his own.
