Mnemonic symbol: a beggar from ancient Egypt. The beggar from ancient Egypt (匃) found work as an elephant (勹) rider. He rides his elephant through the airplane's bathroom (ai4) while the elephant carries a sarcophagus (亾) with his trunk. He doesn't know that Guy Fawkes (g) secretly sneaked into the sarcophagus to hitch a ride.
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.
