数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).

字 = 子 + 宀 : Zorro got a new task from mission control: he is to have an egg standing on its tip. Zorro thinks smart and remembers the egg of Columbus, so he puts the egg in a graduation cap as egg cup and ditches one end of the egg with a huge printing letter. Unfortunately the egg wasn't boiled and there is no gravity, so he messes up the whole bathroom. Mission control can't stop laughing since all they wanted was to fool Zorro into this trick.

信 = 亻 + 言 : Marie Curie and Rosa Luxemburg are reading a letter of Karl Marx to the public in the encampment's bathroom. To make the message really come across to the people they use a megaphone.

号 = 丂 + 口 : Hamlet accidentally locked himself into the aorta's bathroom, together with a mandarin which he is extremely allergic against. His only rescue is the emergency breathing mask attached to the wall which he puts on immediately. There is also a trumpet to call for help with a bugle call, but Hamlet has to wear the breathing mask, so he can't give the bugle call in a normal way. Instead, he has to give the bugle call with his butt.
