燃眉之急

燃 = 火 + 然 : Robinson Crusoe (r) is igniting (燃) a fire (火) in the anthill's kitchen (an2) hoping (燃) to cook his dinner there, but soon people come over and tell him it's not right (然) to do so because of the potential carbon monoxide poisoning.

眉 = 尸 + 丨 + 目 : Mahatma Gandhi (m) and the Eye of Providence (目) fell asleep in the Eiffel Tower's kitchen (ei2), and a ghost (尸) is using the opportunity to play a prank on them. Using a dinosaur bone (丨) which he stuck into black ashes earlier he draws big monobrows (眉) on their faces, using the dinosaur bone like an eyebrow pencil (眉).

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.

急 = 刍 + 心 : Joan of Arc just arrived at the space station and although she has to go to the bathroom very urgently, she first has to clear the way of a big fluffy heart using a lawn mower.
