Mark Harvey is a local celebrity in his hometown.
He was the man who wore a cape and Batman underwear and jumped on the field at Camden Yards in Baltimore.
It was during the Orioles home opener too!
The crowd went crazy as "Batman" stormed the field and was chased by several police officers.
The best part? He's not being prosecuted. He was taken to the police station and was almost immediately able to be picked up by his friends.
What a lucky guy. With a pretty good bod too!
Check out the video (above) to hear his take on the whole event and see footage of him at the game.
