"Tweek vs. Craig" is the 36th episode of Comedy Central's animated series South Park. It originally aired on June 23, 1999. The last episode aired before the South Park movie: South Park: Bigger, Longer, and Uncut came out.
Meanwhile, all the girls (and Kenny) are in Home Ec. When the teacher tells them that they will be making things that are 'lacy and pretty', Kenny cheers. Wendy explains that she requested to be in shop class, but the teacher tells her that Home Economics is for the pretty girls who won't have to worry about careers and instead will marry a nice man. Kenny cheers even louder at this, eliciting strange looks from the girls around him.
In shop class, Stan, Kyle, and Cartman make a bet over who would win a fight between Tweek and Craig. Cartman confronts Craig saying that Tweek was making fun of him. Stan and Kyle do the same with Tweek. Soon enough, the two agree to fight each other. Mr. Adler takes a picture frame out of his drawer, and begins to daydream about the woman whose photo is in the frame (played in live action by the show assistant writer Pam Brady). It is shown that they were once in love.
The boys go outside to the playground, and are waiting for the fight, raising their bets to 10 dollars. Clyde then tells the three that both Tweek and Craig went home. Stan and Kyle, dismayed by the no-show, go to Tweek's house to see why he went home. Tweek says he realized that he and Craig have no reason to fight, but Stan claims that Craig turned up, and called him a wuss. Tweek agrees to actually fight Craig the next day. Cartman and Kenny go to Craig's house, and convince him to show up to the fight as well.
Mr. Adler returns home from a date with the Home Ec teacher, Pearl. However, she would like to be invited into his home, in the hopes that he would "at least attempt" to have sex with her that night, but he refuses and keeps making up excuses. He then goes in, picks up another picture of his dead fiancée, and starts to daydream some more. The next day, during class, Mr. Adler ends up dreaming about his fiancée again, and it is shown that she was a skywriter whose plane exploded in mid-air and crashed into the ocean, where she then drowned. Clyde breaks him out of his daydreaming by telling him that Tommy got his face stuck in the belt sander and now has no face. When he is sent to the nurse, Clyde asks him about the picture and if the woman pictured is dead. Mr. Adler explains a little, but then dismisses him. After school, the fight is about to take place, when it is revealed neither can fight; the bout is postponed once again until they learn how to fight. Craig learns sumo with Cartman while Tweek is taught to box by Stan's uncle Jimbo. In Home Ec, Kenny is told to transfer to shop class by the teacher. Although terrified at the prospect of being around all the tools, Kenny has no choice (as Kenny has a vision of all the sharp tools that would be around him if he transferred to Shop Class, the music that plays is an excerpt from Baba Yaga, the ninth movement of Modest Mussorgsky's "Pictures at an Exhibition" suite which has also been used in several other episodes).
Eventually, Tweek and Craig are ready to fight. Meanwhile, in the shop classroom, Mr. Adler writes a suicide note explaining he can't cope since he has run out of nicotine gum and that the kids all "screw around too much". He then gets on the moving table saw, sets it running, and waits for his death. Outside, the two boys are tired, but Kyle says that Craig just called Tweek a "boner". They continue to fight. Kenny goes to the shop classroom, since he is sent to start work on the jigsaw. Tweek and Craig then are propelled through the shop classroom window, still fighting. Mr. Adler starts up and demands to know what's going on. Tweek and Craig knock the stool out from underneath Kenny, and Kenny hangs on the saw machine. Tweek slams Craig into a second saw which knocks over the one Kenny is on. Kenny's jacket is caught by the blade, spun around and then flies into a box of damp, old, rusty, sharp, nails.
When Mr. Adler picks up Kenny's body, his fiancée talks to him through Kenny's hood, telling him to move on, and his uncle and grandma turn up too. He says he can move on now, and hugs Kenny. Stan says, "Dude, this is pretty fucked up right here." They then go to the hospital to visit Tweek and Craig to tell them about the bet. At that point, Craig severely flips them off, which they accept. They then tell Tweek and Craig that both families called each other wusses on the news, and whether or not this is true, it causes another fight between them.
