經世

经 = 纟 + 又 + 工 : Joan of Arc is boiling with indignation when she sees a silk worm (or rather a book worm?) looking out of a hole in her sacred tome in front of the engine. To drive the worm out, Joan of Arc attached a boxing glove to a steel beam and gains momentum for her sucker punch.

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.
