眾所週知

众 = 人 + 从 : Neanderthal Man (人) and Julian Giant Squid (zhu) are helplessly watching the engine's bathroom ((e)ng4) being flooded by a crowd (众) of rubber chicken (从).

所 = 戶 + 斤 : Susan Saint Bernard and her whole family are weight lifting in the place of the observatory. They are all together lifting one barbell.

知 = 口 + 矢 : Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).
