"Instant Karma's gonna get you, gonna knock you right on the head." John Lennon's lyric has never been so true than with this failed burglar.

Some guy tried breaking into a restaurant in Suitland, Maryland a few weeks ago. He had managed to get inside the building and planned to throw a brick through the window in front of the counter. Then he could get back there and rob the place.

What the burglar didn't realize is that the window was made out of bulletproof glass. When he threw the brick, it bounced right off the window and nailed him in the face. He immediately went down like a ton of bricks.

The police just released the surveillance footage of him getting knocked out and eventually running away empty handed. Cops are asking people to report anyone with a "suspicious head injury."
