于归之喜

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.

归 = 刂 + 彐 : Gitta Giraffe (gu) was given the responsibility (归) to guard the Eiffel Tower. In front of it (ei1) she stands guard holding a tiny kitchen knife (刂) in her hand in case of attacks, and a pig's snout (彐) on her head as kind of a helmet.

之 = 丶 + Z : Mnemonic symbol: Sooo sleepy... "zZz" (the character looks like a "Z"). James II of England (zh) fell asleep in front of the space station (Ø1). He sleeps on a big petal leaf (丶), making loud "zZz" (之) sounds.

喜 = 壴 + 口 : Mnemonic symbol: 喜宴, wedding banquet.

Marie Curie is overjoyed to announce her marriage in the space station. She improvised a wedding banquet with nothing but mandarins and notifies everyone by beating a large drum very quickly with two mandarins.
