This is some awesome community service from a kick-butt family.

The An family has run a family-owned Taekwondo studio for years in Katy, Texas. The Ans were opening up their storefront for evening classes when they heard a woman's screams nearby. At first, they thought it might be a joke, or nothing serious, but one final scream rang through and the family of Taekwondo experts sprang into action.

The five family members, mom and dad, led by the middle child along with his brother and sister, ran towards the screams.

His family ran to the store and opened a door. There they found a man on top of a young woman with his hands "in [in]appropriate places" as she attempted to fend him off, An said.

Okay, so I know it's a serious story and no laughing matter.

But imagine the shock of this creep.

Five Korean people bust through the door - all of them fourth-degree black belts - and they just start wailing on you.

You just woke up on the wrong side of a Kung Fu movie!

Here's how I imagine this guy looked after about five seconds:

The dad yanked the attacker off of the young lady and pinned him to the ground immediately. The sister took the woman being assaulted and led her away from the scene.

'It just happened so sudden,' said An, who has been practicing taekwondo for 16 years. 'It was all self-defense. The intruder was trying to run away — scratching, biting, anything he could do.'

But An's dad, a taekwondo grand master, held down the attacker for 10 minutes until law enforcement arrived, he said.

'My dad is strong. He expected us to protect him,' An said. 'He had a lot of trust in us.'

The Harris County Sheriff's Department recognized the An family for their heroic actions. The perp has been charged with attempted sexual assault and unwanted detention.

It's always heartwarming to see the good guys win one.
