Sometimes, if you don't succeed, you should not try again.
A car thief recently learned that lesson.
In the video above, someone threw a brick at a car window to get inside. The person tried twice without success. He moved to other side of the car, and his plan backfired as the brick bounced back and knocked him out.
A few minutes later police arrived and arrested the man.
If the video above wasn't enough for you, watch the YouTube video to see not one but two suspects get knocked out in a similar yet more hilarious instance.
