Beavis and Butt-head are in the woodworking classroom. The teacher demonstrates how to safely use a table saw by slowly feeding a wooden board through its blade. Beavis and Butt-head become excited when they witness this. After the teacher says to finish working on birdhouses by Friday, the duo begins goofing off. They first feed the boards they are holding through the saw, and then their safety goggles are next to go. Beavis and Butt-head go searching for other things to saw in two. They feed everything through the saw: two books, the telephone, a portrait of the teacher with his family, a sandwich bag with a sandwich in it, the teacher's lunchbox and thermos, the first-aid kit, and the teacher's chair. The teacher finally catches them as they try to lift his desk. As Beavis watches the saw rotate, he starts going into some sort of trance, where he puts his right index finger in front of the blade and ends up severing his finger. As Butt-head is getting lectured by the teacher and the teacher angrily informing him and Beavis that they will fail his class if they continue goofing off, both turn at the sound of Beavis screaming in pain, and notice that Beavis' finger has been severed. The teacher becomes panicked, as Beavis is now bleeding severely, but is unable to use the med-kit or use the phone to call an ambulance, since both had been destroyed by the duo.
The next shot shows the duo in the Nurse's office. The school nurse tells Beavis that she has called the ambulance and that they are on their way. She then says to put the severed finger in some ice while she goes to get some painkillers. Butt-head takes the finger out and starts playing around with it, even though Beavis tells him to stop. Butt-head sticks the finger up his nose and sniffs it. When he realizes it smells funny, he asks what Beavis was doing with it while Beavis scratches his rear. The duo are seen in the hospital room. The physician tells Beavis that they were able to reattach his finger, and that it will not be fully functional for 10 to 12 weeks (70 to 84 days). As Beavis starts picking his nostril with his bandaged finger, it comes off! Beavis starts bleeding again, and the episode ends with him and Butt-head laughing while the physician freaks out.
