“Jackass” ringleader Johnny Knoxville (nee PJ Clapp of South Knoxville) will guest star in the season finale of the animated comedy “King of the Hill.”

In the episode, “Life: A Loser’s Manual,” Luanne’s long-lost father and Peggy’s brother, Hoyt (Knoxville), a two-strike felon, comes to town and commits yet another crime. Luanne’s husband, Lucky (Tom Petty), feels for Hoyt and takes the blame.

The episode airs at 8:30 p.m. on Sunday, May 18, on Fox.

This marks the second time Knoxville has done a guest voice for “Hill.” Two years ago, he played a happy-go-lucky guy whom Bobby Hill idolized.

Knoxville has a personal connection to “Hill.” He is close friends with the series creator, Mike Judge.
