未可

未 = 一 + 木 : Shortly after finishing a new installation in the Eiffel Tower's bathroom, Ai Weiwei is imprisoned by Willy Walrus, because—out of all places—Ai Weiwei put his new installation right into Willy Walrus's toilet. Ai Weiwei's installation is a Christmas tree with a tiny, slightly tilted flute on top. Ai Weiwei would really, really like to correct the tilted flute, but so far, Willy Walrus has not yet let him out.

可 = 丁 + 口 : Karl Marx (k) is challenging his abilities (可) in the elevator's living room (e3). He tries to force a nail (丁) into a mandarin (口), just by using his head. On top of that he tries to do so one thousand times, in order to create a bed of nails (mnemonic symbol for 可).

可 = 丁 + 口 : Alternative mnemonic symbol: kebab, from the pronunciation "ke". Karl Marx (k) is preparing a kebab (mnemonic symbol for 可) in the elevator's living room (e3). He also skewers mandarins (口) on the long steel nails (丁) and will only allow (可) his guests to eat the rest of the kebab if they eat their mandarins first.
