South Park creators Matt Stone and Trey Parker have been hit with a copyright infringement lawsuit over the use of a character in a 2007 episode of the animated show.

Exavier Wardlaw has filed suit against the pair for including a character called The Lollipop King in a three-part Emmy-winning installment, titled Imaginationland.

In the documents filed in federal court in Pennsylvania, Wardlaw's lawyers claim the character is a rip-off of his own creation, the Big Bad Lollipop from a show he came up with called The Lollipop Forest.

He goes on to allege the inclusion of the character in the controversial comedy tarnishes the image of his creation due the show's "unwholesome language and sexual innuendo."

Wardlaw is suing for copyright infringement, according to TMZ.com.
