刻写

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."

写 = 冖 + 与 : Marie Curie (xi) finds the sleepy black horse (与) sleeping during a party in the elevator (e3). As it is the custom, she writes (与) on the sleepy black horse's body with a white felt-tip pen. She also decorates his head with a cooking top (冖).
