自卸车

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).

卸 = 𦈢 + 卩 : Mnemonic symbol: cotton pads.

Marie Curie (xi) bought some lunch-to-go (𦈢), but in the elevator's bathroom (e4) she trips and pours her lunch over the barrier (𦈢). Normally she would use cotton pads (卸) to remove (卸) the mess, but since she doesn't have them, she uses a baby seal (卩) instead.

车 = 七 + 十 : Charlie Chaplin (ch) is parading in a cabriolet (mnemonic symbol for 车) in front of the elevator (e1), because he wants to establish his new cult. Like all successful leaders, he takes the carrot-and-stick approach: In one hand he's waving with a seven-branched laser sword (七), in the other one he's waving with a cross (十).
