微 = 彳 + 山 + 一 + 几 + 攵 : Mnemonic symbol: a microscope.

Willy Walrus set up his microscope on a small table in front of the Eiffel Tower. He is investigating a very interesting crystal: the crystal looks like a big flute, and when he chips off pieces with a sledgehammer they also look like little flutes. He stores the chips in a black sneaker and to put them under the microscope he uses a fork.

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.

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.
