- Stan and Kyle wore their winter hats to the water park but Stan takes his off, albeit only in the wavepool part.
- Cartman further displays his racism as he sings a song about being against Native Americans, Asians, Mexicans, and African-Americans.
- During this song, Cartman says "authorities" without adding the emphasis "authori-tah" at the end. This is probably due to the fact that he was singing, and needed the words to rhyme.
- This is one of few episodes in which Kenny is seen without his parka on. However, as per usual his face is hidden, by the other children, camera angles etc.
- Kenny's hair is a lot "fuzzier" than normal in this episode. However, in the promo pic, it was the closest to the original style from South Park: Bigger, Longer & Uncut, despite changing in the later episode, "The Jeffersons". In the water park his face is covered by positions of other boys, the other time his diving goggles and snorkel or is seen from behind.
- It is shown that Cartman believes that everyone has until 2012 to live, which some thought would be the 'end of the world'.
- The games in Pi Pi's Game Hut are:
- Thirst for Blood
- Abu Ghraib - A Breakout clone, featuring two paddles, but only one joystick and two buttons.
- Junkie Hunt
- Zombie Fighter - Appears to be some horrid lovechild of Space Invaders and Galaxian.
- Whack a Duck - A Whack a Mole knock-off, but with ducks instead of moles.
- This episode is ironic for Kyle as in "Summer Sucks"; he, Stan, and Kenny openly mock Cartman for learning to swim in the public pool, because the first graders pee in the pool. In this episode, however, he is openly horrified at the idea of people peeing in the water and ends up being forced to drink and swim in nearly pure pee, while the others (including Cartman) remain unconcerned.
- Butters expresses actual disappointment in the fact that Eric is still alive at the end of the episode, even though Cartman didn't do anything directly to him in this episode.
- The commentary for this episode was recorded before the episode was finished.
- Kenny has no lines in this episode and has a small role before his death.
- Unlike "The Ring" and "W.T.F.", Kenny dies early on in this episode.
- Kenny was unhooded 3 times and dies 3 times in this season.
- This was the final episode in the series to have aired in the 2000s.
References to Popular Culture
- This episode is based on the 2009 movie 2012.
- Cartman's subplot may have been a reference to the Template:W.
- The part where Kyle has to drink three cups of urine so he can swim to the depths without getting squashed by the fluid pressure is a reference to the movie The Abyss, where the main character has to breath in fluid oxygen so his lungs wouldn't implode.
- When Randy is holding a red shoe at the end is referenced the ending of the 1993 snowy action flick Alive.
- The head of the fake Statue of Liberty flying to the ground could be a reference to the movie Cloverfield, in which that particular event occurs at the start of the monster attack (used heavily in advertising for the movie).
- It appears that Kurt Russell is one of the firefighters that responds to the Pee Crisis - Russell played a firefighter in the 1991 film, Backdraft.
- When the scene starts where the boys are in the wave pool, Kenny is wearing goggles; but when Stan starts talking, he is not wearing them.
- In the wave pool, Stan has taken his hat off but later, when climbing the Everest ride to escape the pee meltdown, he has it back on. He had also been wearing it in another pool while Kyle was still unaware of the pee.
- Cartman was shown with four fingers and five toes.
- During the disaster, although it looked like most parts of the water park were flooded, there were some shots that had no flooding in the specific area at all (ex. the arcade, wave pool).
- While The Boys are on the way to Pi Pi's Splashtown, Jimmy was seen with his usual outfit when his head pops up, in a few seconds later, he was seen in his swimsuit during the close up shots of him.
Kenny drowns in the pee, making his third and final time he dies in Season Thirteen (the first 2 being "The Ring" and "W.T.F."). In contrast, the first two times he died near the end of the episode, this time he died earlier on. This is also the third time in general South Park history that he dies unhooded.
- There is a Visitor at the end of the episode by the ambulance, holding a banana, with swimming trunks and sunglasses. He disappears in the next shot.
