过眼云烟

云 = 二 + 厶 : Yu the Great (yu) had a little accident in the encampment's kitchen ((e)n2). She blew up her capacitor (二), and now there's smoke (云) everywhere. To be able to breathe, she puts on her fake nose (厶).

烟 = 因 + 火 : Maud Younger (y) is giving René Descartes (因) fire (火) for his tobacco (烟) pipe in front of the anthill (an1).
