玉米

玉 = 丶 + 王 : Mnemonic symbol: a jade bracelet.

Yu the Great (yu) and Martin Luther King (王) invented some kind of wrestling sport in the space station's bathroom (Ø4). Both fighters have to be restrained by large jade bracelets (玉) around their body restricting their arms to be aligned to the body. Then they fight. To make things safe they stuffed the space station's bathroom (Ø4) with cosy petals (丶) so that they won't hurt themselves.

米 = 丷 + 木 : Mnemonic symbol: a sack of rice.

Marilyn Monroe and the mean crocodile celebrate Christmas with a Christmas tree inside of the space station. Coincidentally they got each other the same present: each of them is giving the other one a sack of rice.
