中岳

中 = 丨 + 口 : 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.

岳 = 丘 + 山 : Yu the Great (yu) buried his wife's parents and paternal uncles (岳) in the elevator's bathroom (e4). For each of them he set up a small mound (丘), and his wife's parents got the highest peak of the mountain ridge (岳). It was very hard for him to pile up the mounds because he used a fork (山) to do so.
