夠用

够 = 句 + 多 : Guy Fawkes (g), the grammar nazi (句) and Manny Kant (多) want to play sheepshead in the outhouse's bathroom, but they're not enough (够) people. They are only enough (够) for skat.

This mnemonic may be a little lame, but it has to be enough (够). I have been thinking about the above sentence (句) many (多) times.

用 = 丨 + 月 : Mnemonic symbol: a first aid kit. Can you see the cross on the container?

用 = 丨 + 月 : Yu the Great hurt her leg when she slipped in the engine's bathroom. The moon helps her to splint her leg using the bathroom's first aid kit and a dinosaur bone.
