曠日持久

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.

日 = 囗 + 一 : Robinson Crusoe (r) is hiding from the sun (日) in an enclosure (囗) full of flutes (一) in the space station's bathroom (Ø4).

持 = 寺 + 扌 : Charlie Chaplin brought his Buddhist shrine to the space station, but just inside the entrance he realizes that he didn't think of zero gravity as his shrine is about to float away. His only option at the moment is to grasp the shrine with two toy claws and manage it this way.

久 = ㇏ + 勹 : Mnemonic symbol: hourglass.

久 = ㇏ + 勹 : Joan of Arc and the elephant are visiting the outhouse, and they have been looking at the Mona Lisa for hours. Impatiently, Joan of Arc looks at her hourglass telling them that they have been standing there like that for three and a half hours, so she's poking the elephant with a finger to tell him to move on.
