Things keep getting worse for actor-comedian Katt Williams. After being arrested several times over the past six weeks -- the most recent a Jan. 8 bust for failing to appear in court -- Williams is now being sued for allegedly refusing to pay for a used car.

It’s an incredibly bizarre story, but, according to TMZ, a Los Angeles man named Khosrow Gharib sold Williams a used 2002 Ford Expedition SUV on Oct. 30, and Williams has refused to pay for it.

So Gharib is suing Williams for $7,500, apparently the Kelley Blue Book value of the Expedition. He also has claimed he has spent a significant amount of time trying to get Williams to pay.

But this whole lawsuit brings up one very interesting question: Why is supposed millionaire actor-comedian Katt Williams buying an 11-year-old SUV? And why can’t he afford to pay for it? These are questions that may never be answered.

Meanwhile, Williams was arrested in front of his Los Angeles home last Tuesday after failing to appear in court on a matter related to an earlier arrest involving a police chase in Sacramento, Calif., TMZ reported.

Williams apparently missed a Monday court hearing in the California capital, and a felony arrest warrant was quickly put out on the “Scary Movie 5” star. TMZ said Williams knew there was a warrant out on him and cooperated with police during the arrest.

Williams was previously arrested in Northern California on Dec. 8 as a result of leading police on a bizarre chase across Sacramento on Nov. 25. He posted bail that Sunday afternoon after spending the previous night in the Yolo County Jail.

During the chase, Williams drove a three-wheeled motorcycle on the wrong side of the road. He allegedly came close to hitting five pedestrians during the bizarre joyride.

While police abandoned the chase in the interest of public safety, they put out a warrant on the comedian and arrested him in early December, the Sacramento Bee reported.

In addition to Williams’ arrests related to his Sacramento joyride, the comedian was arrested on Dec. 28 for child endangerment. A police raid found large amount of illegal drugs and guns, and the actor’s four children were taken away.

"How do you keep kids safe without guns?" Williams asked TMZ -- presumably rhetorically -- when it questioned him about the arrest. "If the police come in and raid my place and break into my gun boxes, you're gonna find guns! I'm not in a gang -- what difference does it make?"

In addition to Williams’ criminal-law struggles, he is also being sued for a botched standup performance that took place in mid-November.

The class-action lawsuit targets both Williams and his show’s promoter, Live Nation, for a performance in Oakland on Nov. 16, TMZ reported. The lawsuit was filed by Brian Herline on Nov. 22.

According to the suit, Williams was onstage for all of 10 minutes before storming offstage. Reportedly, he delivered almost no comedic material during that time, but instead "confronted a heckler, took his clothes off, and attempted to fight at least three audience members."

Apparently, fans were extremely disappointed by the “nonperformance,” which explains the legal action being taken against Williams. In recent years, Williams has become known for bizarre behavior at his standup shows. And elsewhere.
