月缺

月 = ⺆ + 二 : Yu the Great (yu) is modelling a moon (月) in the elevator's bathroom (e4). He uses a stapler (⺆) to staple a lot of capacitors (二) together to form a moon shape, while the real moon is sitting for him.

缺 = 夬 + 缶 : Cupid (qu) has almost all pottery pots (缶) of a collection of twelve, but the seventh piece is missing (缺). He asks a crystal ball (夬) I'm front of the elevator (e1): where is the missing piece? The crystal ball replies that he smashed it when he came back totally drunk the night before.
