旷世

旷 = 广 + 日 : The sun (日) is lecturing Karl Koala (ku) in the anglepod's bathroom (ang4), but Karl Koala rather skips class (旷) by hiding under a wide (旷) parachute (广) and playing video games in his hideout.

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.
