世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.

代 = 亻 + 弋 : Rosa Luxemburg (亻) wants to practice her archery skills in the airplane's bathroom (ai4). On the other side Don Quixote (d) is standing, but they don't have an apple, so they substitute the apple with a token (代, 代币). Don Quixote is trembling heavily as Rosa lifts her bow (弋) and prepares to shoot down the token from Don's head.
