Proper Condom Use/Trivia

Trivia

 * The Jennifer Lopez doll and car Stan and Kyle were playing with in the beginning is the same one from the episode Cartmanland. In this episode there are burn marks already on the car, caused by the firecracker the boys stuck in it.
 * The sex positions that Mr. Garrison describes – Hot Carl, Hot lunch, Filthy Sanchez, Glass bottomed boat, Fish Eye, Pile driver, Donkey Punch and Chili dog –are real, and many involve anal sex and/or feces.
 * In Australia, this episode received an MA rating (similar to the TV-MA rating on American TV) as opposed to the usual M rating (similar to the TV-14 rating on American TV), due to is strong sexual content throughout the episode and the graphic violence near the end of the episode.
 * When Chef is stating that sex shouldn't be taught by people with no understanding of it, people with a bad opinion of it, or complete perverts, the camera pans to Mr. Mackey, Ms. Choksondik and finally to Mr. Garrison, who asks, "W-why did you pan to me just now?", breaking the fourth wall.
 * According to DVD commentary, the Comedy Central censors told Trey and Matt to drastically shorten the part where Mr. Garrison demonstrates how to put on a condom by using his mouth with a condom around the lips and deep-throating the model penis used in the lesson.

Goofs

 * When Cartman says "Red Rocket" as he and Kenny shows Stan and Kyle how to "milk" a dog, his mouth moves but he doesn’t speak. This was later corrected in the Comedy Central reruns, but not on the season five DVD.
 * In this episode, it is implied that Mr. Mackey had limited experience with sexual intercourse: first when he is teaching sex-ed to the students; again talking to Ms. Choksondik, planning their sex-ed curricula; finally, on the closing of the episode, Chef says that Mr. Mackey doesn't know anything about sex. However, in the episode "Ike's Wee Wee", it is implied that he has sexual intercourse, and subsequently marries a rather attractive woman. Also, in the episode "Cat Orgy", it’s implied that he is going to have sexual intercourse with Mrs. Cartman. In "Something You Can Do with Your Finger" we see a video clip of Mrs. Cartman and Mr. Mackey involved in bondage, however, they weren't engaging in intercourse.
 * The child who was shot with a nail gun is first shown with brown hair, but in another shot, has red.
 * Clyde has a different father in the episode.
 * When Mr. Garrison is talking about condoms with the kindergartners, Ike doesn't have a mouth.
 * While Butters is putting his condom on, he reads the instructions, but Kyle's voice sounds like Butter's when he asks him a question directly after.

Kenny's Death

 * Kenny is killed by Bebe after Butters' speech from a boomerang. His death sparks off the beginning of the conflict.

Hidden Visitor(s)

 * Two visitors can be seen watching Butters putting on a condom in a tree.
