Katt Williams Kicked Out Of His Show

Katt Williams got so belligerent toward the crowd at his own comedy show last night, the club had to kick him out -- and then called the cops on him when he tried to get back in!

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

Katt was 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 tonight as well, but he has since been removed from the Improv's website.

Calls to Katt's people were not returned.
