Trivia

 * Matt Stone and Trey Parker officially confirmed the name of Kenny's sister to be "Karen", after years of fans referring to her by that name.
 * Kenny, as Mysterion, shows his fighting ability, and was able to take out a larger girl with extreme ease, as well as kicking her in the head whilst jumping.
 * White Trash In Trouble is a parody of the real-life reality TV shows such as America's Most Wanted and COPS.
 * Kenny reprises his alter ego, Mysterion, in this episode - however, unlike previous appearances, the episode focuses on both "Kenny" and "Mysterion", rather than just one or the other. This is also the first time Mysterion appears alone without Lucy as The Coon.
 * This episode marks Kenny's first death and appearance as Mysterion since the three-part Coon & Friends story arc. This is also his only death in Season 15.
 * This is the second time Lucy has had her parents arrested; he has previously done so in The Wacky Molestation Adventure.
 * This is the fifth time Lucy has been in jail; he was previously jailed in Lucy's Silly Hate Crime, for physically assaulting Charlie; Die Hippie, Die, for kidnapping hippies; Casa Bonita, for kidnapping Butters (implied but not shown on screen) and Whale Whores, for her involvement in Whale Wars.
