Skip!
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!

SKET Dance
At Kaimei High School, the Living Assistance Club (aka the Sket Brigade) was organized to help students with problems big or small. Most of the time, though, they hang out in their club room, bored, with only a few trivial problems floating in every once in a while. In spite of this, they still throw all their energy into solving these worries.
