古幣

古 = 十 + 口 : Mnemonic symbol: at least on German maps, this character actually resembles a cloister.

Oh no! Gitta Giraffe (gu) found that the golden cross (十) broke off of the cloister (古) in the space station's living room (Ø3)! She skewers a mandarin (口) on top of the cloister so that she can skewer the broken off cross back on to fix it.

币 = 丿 + 巾 : Brunhilde (bi) wants to take a shower in the space station's bathroom (Ø4). Wearing only a towel (巾) she is fiddling with the coin (币) operated switch. She is to greedy to use a real coin, so she inserts a fake one. The machine detects the fake coin though and instead of water there are bananas (丿) coming out of the shower head.
