大言不慚

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

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.

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.

惭 = 忄 + 斩 : The King of Chu (c) just entered the anthill (an2) and is very ashamed (惭). He got his flail (忄) stuck in his lawn mower (斩) and now he cannot get it out, so he has to ask his friends for help, which is really embarrassing for him.
