口不择言

Mnemonic symbol: 口 shall be represented by a mandarin. Karl Marx (k-) is enjoying a mandarin in the outhouse's living room (ou3).

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

择 = 丨 + 又 + 扌 + 二 : Zorro (z) has to select (择) his new weapon between two terrible choices (择) in the elevator's kitchen (e2): there is either a boxing glove (又) or a dinosaur bone (丨). He has to select one using a toy claw (扌), but he has to choose wisely: one of the items is hooked to a charged capacitor (二) which will shock Zorro should he take the wrong choice (择).

言 = 亠 + 二 + 口 : The horizontal lines look like sound waves that emerge from an opening: I'll resemble 言 by a megaphone.

言 = 亠 + 二 + 口 : Maud Younger rushes into anthill and in the kitchen she uses a megaphone to loudly announce that the world revolution will soon start. She also tells the people that she has berets for everyone so that everyone will be able to be in style for the revolution. However she doesn't tell that she prepared the berets in another way: to each beret, she attached a mandarin via two capacitors which forms a formidable antenna, so that after the revolution, she'll be able to transmit her speeches directly to the wearers' brains.
