崖刻

崖 = 厓 + 山 : Maud Younger (y) has been eating chocolate bars (厓) with a fork (山) in the ashram's kitchen (a2) for hours now. She throws the packaging just over her shoulder, where already a precipitous (崖) cliff (崖) has formed from all the plastic.

刻 = 亥 + 刂 : Mnemonic symbol: an engraver.

The boar cannot believe it when it meets Karl Marx in the elevator's bathroom! Bewildered it asks for an autograph but has nothing except for a kitchen knife and an engraver. It takes Karl Marx a quarter of an hour to engrave his message in the kitchen knife: "Dear boar, keep on fighting capitalism! Yours, Karl."
