弃若敝屣

弃 = 亠 + 弁 : The Queen of Hearts (qi) made a vow to not wear any hats anymore in the space station's bathroom (Ø4). She thus throws away (弃) her caps (弁) and her berets (亠) by throwing it out of the window into outer space.

若 = 艹 + 右 : Mnemonic symbol: a wooden chicken as in 呆若木鸡, "dumb as a wooden chicken".

A nazi wants to beat up a wooden chicken in the observatory's bathroom for being different, but just as he charges across a sheet of artificial lawn Rachel Rhinoceros pulls she sheet from under his feet and lets him topple head-first to the ground. She thinks that the nazi is truly as dumb as a wooden chicken.

敝 = 米 + 冂 + 攵 : Mnemonic symbol: a pair of old worn-out shoes.

Brunhilde (bi) has been on a treasure hunt for weeks now because she found an old map (冂). For her hunt she brought a sack of rice (米) which she already more or less used up. After digging up the floor of the space station's bathroom (Ø40) with a sledgehammer (攵) at the point indicated on the map, she finally finds the treasure: a pair of old worn-out shoes (敝) which were incredibly valuable to the owner, but are worthless for Brunhilde.
