*As first reported by HumorMillMag.com Saturday night, used-to-be-funnyman Katt Williams got so belligerent toward the crowd at his own comedy show, the club had to kick him out — and then called the cops on him when he tried to get back in!

Here’s what tmz is reporting:

Katt was scheduled to perform two shows at the Improv in Ontario, CA last night — but according to our witnesses, he got tossed from the 8:00 PM show and the 9:30 PM show was cancelled.

In crappy amateur video that you can hardly see here, Katt is being escorted out by police and trying to explain what happened to the crowd outside waiting for the second show. They did not seemed pleased.

Katt was scheduled to perform Sunday night as well, but he has since been removed from the Improv’s website.

Calls to Katt’s people were not returned.

HumorMillMag.com said Saturday night’s shows also had comedians Gina Yashere and Maronzio Vance. They carried on without Williams and probably got enough material from the incident for a couple of new routines of their own.
