玉莖

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.

茎 = 艹 + 圣 : Joan of Arc (ji) wrote to Father Christmas (圣) that she wants a condom (茎) for her penis (茎), but instead Father Christmas only understood she wants a lot of stems (茎) so in front of the engine ((e)ng1) he hands her a sheet of artificial lawn (艹).
