In a Butters-centric episode of 'South Park' (Wed., 10PM ET on Comedy Central), our intrepid hero was diagnosed with multiple personality disorder. It's the kind of multiple personalities all kids display when they're playing make-believe and pretending to be a truck driver or an inspector.

In truth, his therapist was the one suffering from the disorder. One of his personalities, a child named Billy, called on "Inspector" Butters to help him, and led him to the therapist's house. There the parallel stories of the episode culminated in a rather impressive twist.

The therapist was actually Tuong Lu Kim, the owner of South Park's City Wok Chinese restaurant. And he was never even Chinese. So people who thought it was a horrible fake accent by a white dude can rest easy, because now it really was in the show too.

It turned out to be a great twist and an unexpected turn for the long-time character. A turn that apparently will remain lurking inside of Kim, as the police decided it was better to let him continue thinking he was a Chinese man. After all, City Wok is the only Chinese restaurant in South Park. Wouldn't want to lose that.
