自由泳

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).

由 = 丨 + 曰 : Mnemonic symbol: 自由古巴， a cuba libre. The character 由 itself even looks like a cuba libre.

Maud Younger (y) is taking part in a charity auction in the outhouse's kitchen (ou2). She is auctioning the dinosaur bone (丨) next to her and is speaking into a microphone (曰). In the other hand she is holding a cuba libre (由), and she is already quite drunk.

泳 = 氵 + 永 : Yu the Great (yu) is swimming (泳) through a sea of diamond rings (永) inside of the engine ((e)ng3). It is very exhausting, so she often has to take sips from her water bottle (氵).
