Do not piss off Batman.

Michael Keaton shut down an Atlanta Braves fan and heckler at the MLB team's game against the Pittsburgh Pirates at Turner Field in Atlanta on Friday...and he basically didn't have to say a word.

The 63-year-old actor, a Pennsylvania native and longtime Pirates fan, had watched the man heckle center fielder Andrew McCutchen and then confronted him, Pittsburg's WPXI-TV and Yahoo! Sports reported. Keaton was photographed looking at the heckler and pointing at the scoreboard. The Pirates beat the Braves, 10-8. Burn!

The Braves did, however, beat the Pirates the following day, with a score of 5-4.
