全世界

全 = 人 + 王 : In the anthill's kitchen (an2), Neanderthal Man (人), Martin Luther King (王) and Cupid (qu) have gathered for a world record attempt. They want to eat a whole (全) 100 kg whole-wheat bread (mnemonic symbol for 全) in under one hour.

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.

界 = 介 + 田 : Joan of Arc wants to leave this world and sets up a rocket launch field in the elevator's bathroom. The field looks like a normal crop field, except that there's a rocket in the middle and that the Joan of Arc marked the boundary with white and red tape.
