满世界

满 = 两 + 氵 + 艹 : Mahathma Gandhi stuffed the inside of the anthill with artificial lawn. Everyone is extremely annoyed by this packing, but as he sprinkles water out of a water bottle on the artificial lawn, it dawns on them: he smuggled taels of gold in the lawn, which slowly grow out of the lawn as he distributes the water and laughs happily. The whole anthill is soon full of golden taels.

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.
