走來回

走 = 龰 + 土 : Mnemonic symbol: a Nordic walking pole. Zorro (z) is fighting Neanderthal Man (bottom of 龰) in the outhouse's living room (ou3). Neanderthal Man uses his pennant (top of 龰), and Zorro uses a Nordic walking pole (走). Zorro overcomes Neanderthal Man by using a dirty trick: he throws some dirt (土) at Neanderthal Mans face, who is blinded and hurts his foot with his pennant (the pennant pierces his foot: 龰). Just at this moment Zorro uses the opportunity to sedate Neanderthal Man and rams a syringe (龰) into his shoulder.

來 = 从 + 木 : Mnemonic symbol: mailwoman. Sir Lancelot (l) is visiting the mailwoman (來) in the airplane's kitchen (ai2). As a gift, he brought a Christmas tree (木) decorated with rubber chicken (从).

来 = 丷 + 未 : Mnemonic symbol: mailwoman. Lancelot (l) is super happy that his inflatable crocodile (丷) and live size Ai Weiwei (未) puppet finally arrived (来). The mailwoman (来) delivered them straight to the kitchen of the airplane (ai2).

回 = 口 + 囗 : Helga Horse (hu-) smuggled herself into the Eiffel Tower's kitchen (-ei2). She covered herself in an enclosure (囗) full of mandarins (口). Unfortunately, she missed one little detail: The box full of mandarins is to be shipped back (回) to China soon.
