Antonio Brown has no chill.

After the Pittsburgh Steelers wide receiver took a punt back 70 yards for a touchdown that put his team up 45-10 and iced their win by the same score, Brown got a little ... excited with his celebration.

As if the celebration alone wasn't excessive enough, he also scared the living daylight out of the security guard in the process.

To be fair, the awkwardness of how he landed and fell was kind of funny, especially considering the type of pain he might have been in. Even the referees couldn't contain themselves.

Not bad, Antonio.
