赛特

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).

特 = 寺 + 牛 : Tecumseh has a very special mount: In contrast to the other Indians he rides a bull. Moreover, the bull is so special that it meditates in front of the Buddhist shrine in the elevator's bathroom together with Tecumseh.
