September 10, 1997
Stan contends with his violent, older sister, Shelley, while Kyle sets out to crossbreed an elephant with a pig.
"An Elephant Makes Love to a Pig" contains examples of:
- Braces of Orthodontic Overkill: Shelley
- Double Standard: Abuse, Female on Male: The kids at school feel bad for Stan's abuse...until they find out his sister beat him up and make fun of him, never mind that Shelly is a dangerous psychopath.
- Early-Installment Weirdness: In this and a few other episodes, Kyle is the one to recite both catchphrases after Kenny's death. Although, Stan was a little busy at the time.
- Kevin Stoley is referred to by the name "Casey", while the storyboards for season 1 had identified him as "Sky".
- Executive Meddling: The original production title was "An Elephant Fucks a Pig", but Comedy Central ordered it to be toned down. Trey Parker and Matt Stone expressed annoyance with the change in an early introduction video for the episode (seen on the 1998 VHS). This title is also used in the DVD commentary.
- A scene was cut that involved Shelley lighting Stan on fire and soaking him with a bucket of water (only to repeat the actions twice more). It was removed so late in production that a puddle still inexplicably appears underneath Stan after she's thrown him. Comedy Central censors had ordered the scene cut in out of fear of a repeat of the Beavis And Butthead-"little kid plays with fire and his parents blame the show for it" controversy.
- Off Model: One portion of the cafeteria scene suddenly reverts to the paper cut-out style used in the pilot. This is due to the fact that it was a recycled scene from the unaired version of the pilot, and the creators decided to place it in this episode.
- Write Who You Know: Trey Parker based Stan's bad luck with his sister on his own childhood experiences with his older sister Shelley Parker (who did punch him, throw him down the basement stairs, and lock him out of the house a lot. The other abuse, like the TV electrocution, the burning from the deleted scene, and the lawn mower part near the end of the episode, are exaggeration). However, her braces are based on Matt Stone's sister Rachel.
