赤字

赤 = 一 + 亦 : Mnemonic symbol: a red letter.

Charlie Chaplin (ch) finds that the also-ran (亦) ran over his flute (一) in the space station's bathroom (Ø4) bare-footed (赤). Angrily he gives the also-ran a red letter (赤).

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.
