3. The Heath Herring Kiss Punch
Maybe not the worst on this list, but probably the most famous. In fact, if memory serves, this video went viral before anyone knew what going viral meant.
The best part is that Herring knocks The Kisser absolutely cold with what looks at a glance like an open-handed slap, like some indignant woman who didn't care for the young man's advances.
I never get tired of watching this.
