Kyle and Stan are unable to answer her, claiming: "You know, They. They're bastards." Frustrated, Kelly asks them to help Kenny, but the two are fulfilling their usual role on the show, outraging Kelly even more. She then desperately attempts CPR and successfully saves Kenny, to the amazement of Stan and Kyle. With this result, Kenny has successfully survived an entire episode for the second time (the first time being "Mr. Hankey, the Christmas Poo"). When the group escapes the forest, Miss Stevens and the children are so happy to leave the jungle that they change their tune: different lyrics are applied to the original song, which now rebukes the rainforest rather than praises it. It meets with a positive response from the audience, as if they were still singing rainforest activism. The episode ends with a message telling people about the dangers of the rainforest and to help stop it. Despite the episode airing in 1999 in the U.S. and a few years later in Latin America, the episode caused some controversy in February 2007 over the comments that Cartman made about Costa Rica saying that the town of San Jose "smells like ass" and the way the creators show the country full of "prostitutes, shantytowns, and trash." The Costa Rican Government was reportedly "not amused" with this episode. Andy Patrizio of IGN wrote "Rainforest Shmainforest, is one of my favorites [of the third season]...Hearing [guest voice Jennifer Aniston] lose it at the end, with Stan's line "Now she gets it" was just a hoot." DVD Verdict wrote ""Rainforest Schmainforest" is a hilarious take on Up with People, ecological activists, and foreign cultures". This is the second episode in which Kenny survives the entire time without dying (at least during the era of the series in which he died in nearly every episode), the first being "Mr. Hankey, the Christmas Poo."
