When will it stop?

Reports TMZ:

Just days after bitch-slapping a Target employee last week, Katt Williams unleashed microphone fury on an unsuspecting audience member, knocking the man upside the head with his mouthpiece … HARD … and TMZ has video of the attack.

Katt was performing at the Paramount Theater in Seattle last Friday at the time — and judging from the video, Katt was upset because the victim was recording his show.

Katt subsequently addressed the audience saying, “It could happen to you. Record me and see what happens to you. Go home and get your raggedy pistol and bring it back. I already got mine.”

The victim — a man named Carlos Casto-Lino — has since filed a $250,000 lawsuit against Katt and the theater … claiming Katt gave him a concussion and left him with contusions on his head.

Calls to Katt’s camp weren’t returned — but based on his recent string of crazy behavior, we’re guessing he gives zero craps about anything.

And now…the video.

This is EbenGregory.com…telling you I am suddenly reminded of this video.
