Reverse Cowgirl (South Park)

"Reverse Cowgirl" is the first episode of the sixteenth season of the American animated sitcom South Park, and the 224th episode of the series overall. It premiered on Comedy Central in the United States on March 14, 2012. In the episode, a nationwide catastrophe occurs after Clyde's mother is killed because Clyde forgot to put the toilet seat down.

The episode was written by series co-creator Trey Parker and is rated TV-MA L in the United States. It parodies both the gender-divided social etiquette regarding toilet seats (particularly how most women prefer to have their male spouse or child put down the toilet seat after they use it), and the post-9/11 airport security measures imposed by the Transportation Security Administration. In this episode, Clyde's mother Betsy is instead voiced by Trey Parker rather than April Stewart.
