:
Willy Walrus (w) just finished digging a grave (亡) for his dead relatives who were killed in the Arctic in the anglepod's kitchen (ang2). Exhausted, he sticks the shovel (乚) in the earth and puts his beret (亠) on it. Finally, he sets up the tombstone (mnemonic symbol for 亡).
亾

人
:
My mnemonic for 亡 is a tombstone, so this ancient variant gets to be a sarcophagus.
Willy Walrus (w) has to bury the Neanderthal man (人) in the anglepod's kitchen (ang2). The Neanderthal man (人) is lying in a half open sarcophagus (亾) next to Willy, and Willy uses a shovel (乚) to dig the grave.
