A man in Waikiki, Honolulu was allegedly fondling himself next to a woman who was trying to get changed.

In case any of you readers out there were planning on touching yourself in public, here's an idea, f**king don't!

The video shows passersby trying to subdue the man. However that's when he pulls the knife. The situation could have escalated and been much worse, but eventually Honolulu police arrive. It's not known if the man was intoxicated, although he definitely looks it.

After not complying with their requests to drop the weapon, the cops go to their stun guns. Word of caution, if you think you're a bada** who's stronger than a stun gun...just watch this video on loop. Dude gets knocked TF out.

Gotta love the celebration from the cheering section as the suspect hits the ground. I can honestly say it's refreshing to see karma instantly doing its job.
