周

周 = ⺆ + 土 + 口 : Mnemonic symbol: a hula hoop. James II of England (zh) performs in front of the outhouse (ou1): he swings a hula hoop (周), juggles three mandarins (口) and balances a small heap of dirt (土) on his head. He cheated a little bit though, because he stapled the heap of dirt to his wig with a stapler (⺆).

冂 = 丨 + ㇆ : Mnemonic symbol from the shape of the character: kind of looks like a map.

Zeus (ju) found a secret map (冂) that tells the location of a golden dinosaur bone (丨) in front of the engine ((e)ng1), so he took a plow (㇆) and dug up everything. He actually found a couple of dinosaur bones, but not a golden one.

Mnemonic symbol: 口 shall be represented by a mandarin. Karl Marx (k-) is enjoying a mandarin in the outhouse's living room (ou3).

吉 = 口 + 士 : Mnemonic symbol: "Giga" apparently stems from a Greek word for "giant", so I'll represent 吉 by a giant.

The giant (吉) just entered the space station's kitchen (Ø2) and is very hungry. In each hand he holds Joan of Arc (ji) and the bachelor (士) captive and robs them for their mandarins (口) which he longs for.

土 = 十 + 一 : Tommy Turtle (tu) wants to fix a cross (十) on a flute (一) in the space station's living room (Ø3). He uses dust and clay (土) to hold them together.

⺆ = 丿 + ㇆ : Mnemonic symbol: ⺆ looks like a staple, as used in a stapler.

Zeus (ju) wants to plant bananas (丿) in front of the engine ((e)ng1). He uses a plow (㇆) to dig up the earth and puts the bananas inside. To prevent the bananas from falling down, he staples them down with a stapler (⺆).
