能够

能 = 匕 + 厶 + 月 : Mnemonic symbol: bicorne hat.

能 = 匕 + 厶 + 月 : Napoleon and the moon are fighting over who's the real Napoleon in the engine's kitchen. They both wield a ladle each. During the battle, Napoleon destroys the moon's fake nose, while the moon dents Napoleon's bicorne hat.

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.
