The students of Kaimei High are going on a class trip, but first, they have to participate in a rope skipping competition to see which class gets the best rooms. Saaya doesn't have an athletic bone in her body, so is worried she's going to doom her class to the worst rooms of all, until the Sket-dan tries teaching her how to skip! Then, the students are on their way, but in the back of one bus, Chuu-sensei is playing mad scientist again, and this time his victims are Bossun, Himeko, and Tsubaki!
I'm in bad shape when it comes to 
competitions, so I'll just watch.
Voy a observar la competencia sin participar.
Soy mala cuando se trata de competir,
 así que me limitaré a mirar.
Não sou boa em competições 
esportivas, então vou só assistir.
