预赛

预 = 予 + 页 : Yu the Great and Zai Yu are preparing their tax reports in advance in the space station's bathroom. Yu the Great is scribbling wildly on one sheet of paper after the other, and sheets of paper are flying all over the place. Zai Yu on the other hand just fell asleep and covered himself in a lot of sheets of paper. He covered himself with a sheet he made out of paper.

赛 = 宀 + 井 + 丌 + 贝 : Socrates (s) and the crab (贝) are competing in a competition (赛) in the airplane's bathroom (ai4). The competition is about stacking wells (井) as high as possible. After time's up, Socrates is the clear winner. He climbs the winner's pedestal (丌) and receives a honorary PhD and thus a graduation cap (宀).
