二部制

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).

部 = 咅 + 阝 : Bruno Bear (bu) has been harassed by the Imperator (阝) in the space station's bathroom (Ø4), so Bruno sets up a trap. He creates two fake boobs (乳部) out of poo-poo (咅) and as the Imperator grabs his boobs, the Imperator realizes his mistake and exclaims "bah!" (部).

制 = 牛 + 巾 + 刂 : James II of England (zh) and the bull (牛) have to work in a sweatshop in the space station's bathroom (Ø4) where they manufacture (制) one printed circuit board (制) after the other. Their only tools are kitchen knives (刂) with which they carve the boards. They sweat a lot, so each of them has a towel (巾) wrapped around their neck.
