自称

自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

称 = 尔 + 禾 : Charlie Chaplin practices eating cereals blindfolded in front of the engine. As he is eating he wonders why the bowl is suddenly so heavy. The reason is that a peace dove sat down on the bowl and eats the cereals as well. The peace dove names Charlie Chaplin a real idiot because he doesn't notice.
