舉世

举 = 兴 + 干 : In the space station Zeus eats some dried fruits as he suddenly finds a sea star in the bag. Baffled, he lifts up the sea star to have a closer look.

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.
