VIDEO: Angry customer head-butts bus, knocks self out

WINTER HAVEN, Fla. -- A bus customer got angry about an extra $2 fare. So what did he do?

Head-butted the bus - and knocked himself out... of course.

According to the driver, the man left the bus at one stop, decided he wanted to travel to a different stop, and got mad when he learned it would be another $2.

The glass on the bus door shattered. The man got up off the ground after a few minutes and ran away.

Police are looking for him.
