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.

舟 = 丹 + ⺀ : Mnemonic symbol: 舟 looks like the tower of a yellow submarine. In front of the outhouse (ou1), James II of England (zh) stands next to his yellow submarine (舟) and asks you: will you swallow the blossom (⺀) and continue your quiet life? Or will you swallow the red pill (丹) and follow him on his adventures in the submarine?
