Mnemonic symbol: a dart board, because you always try to hit the center.
Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.
Hamlet (h) made himself a bowl of cereals (禾) with bananas (丿) and Christmas trees (木) in the elevator's kitchen (e2). He holds the bowl of cereals like he would hold Yorick's skull.
