Rainforest Shmainforest

"Rainforest Schmainforest" is episode 301 of Comedy Central's South Park. It originally aired on April 7, 1999.

Plot
Miss Stevens is in Mr. Garrison's class recruiting students for a tree saving choir tour called "Getting Gay With Kids." The boys cause trouble calling the choir names and belittling their cause and are sent to the office. Kenny has fallen for one of the girls in the choir, Kelly, so when Mr. Mackey punishes the boys by forcing them to join the choir, he is the only one who is happy about it.

The children are on their way to San José, Costa Rica. Kenny meets with Kelly, who calls him Lenny, Benny and any other name that rhymes with Kenny (instead of calling him Kenny). Miss Stevens also tells Cartman that she plans on changing him; she's got a lot of work ahead of her. Upon arriving, the children meet the Costa Rican President and do a preview dance routine, but Miss Stevens is dismayed by Kyle's lack of co-ordination.

On their tour of the Rainforest, the children see the 'wonders' of the Rainforest, which Cartman keeps trying to beat with a stick. Then their tour guide is killed when he is eaten by a man-eating snake. Miss Stevens and the children are on their own in the jungle. They run into a group of revolutionaries, and try to recruit the revolutionaries to their cause, to which the rebel leader replies: "We're not getting gay with any kids" and have to run away when government troops arrive and start a battle. With the group still wandering aimlessly around the rainforest, Cartman deciding to leave "this hippie", walks off and finds a friendly crew working on a deforestation project.

Back in San José, the concert is about an hour away from starting. The President stalls for time by telling Polak jokes. Meanwhile, Miss Stevens and the remaining children find a group of natives intent upon killing them, and sacrificing Miss Stevens. At this point, she finally changes her mind, and decides the rainforest is not such a good place after all, just as Cartman and the construction workers arrive to save everyone. Miss Stevens and the children are so happy to be out of the forest that they literally change their tune about the Rainforest. They do a different version of the original song, which rebukes the rainforest rather than praising it as the original did.

Trivia

 * Miss Stevens, the Choir Teacher, was voiced by Jennifer Aniston.
 * The rainforest guide mentions that the snake on the tree is a coral snake. Coral snakes are not constrictors, meaning that the snake would not have strangled the man and swallowed him whole, but would have bitten him with deadly neurotoxic venom.
 * Kenny almost dies when he lies to Kelly and is struck by lightning. She actually revives him, while Stan and Kyle are dumbfounded. This marks the first time someone has ever tried to resuscitate Kenny, and the second time Kenny survives the whole episode.
 * In the Tony Danza scene, when Kelly asks Kenny to hold her hand, it shows Danza where Kenny should be.
 * Costa Rica hasn't had an army since 1948, being the first country to abolish it.
 * The natives using the choir teacher as a sacrifice is very reminiscent of the scene in King Kong where Ann Darrow is put out as a sacrifice for Kong.
