适中

适 = 舌 + 辶 : Sherlock Holmes (sh) got some new gladiator sandals (辶), but in the space station's bathroom (Ø4) he finds that they don't fit (适) his feet. He does notice however that they fit (适) quite nicely his tongue (舌) if he sticks it into one of the sandals.

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.
