二头肌

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

头 = ⺀ + 大 : Tecumseh (t) is inspecting is depiction in the outhouse's kitchen (ou2). He's depicted as having a skull (mnemonic symbol for 头) head (头) with two petal leaves (⺀) in the eye holes, and having a robot (大) body.

肌 = 几 + 月 : The moon (月) is moving and Joan of Arc (ji) is helping him. She's been carrying sofas and small tables (几) all day in front of the space station (Ø1) and now she has sore muscles (肌).
