不知天高地厚

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

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).

天 = 一 + 大 : Mother Teresa (ti) programmed a robot (大) to play a flute duet together with her in front of the anthill (an1). As they play their flutes (一) an angel (天) hears their heavenly tune and descends from heaven to listen to them.

高 = 亠 + 冋 + 口 : A skyscraper.

高 = 亠 + 冋 + 口 : Just in front of the aorta, a huge skyscraper has been erected. It's an important building, so there's a control checkpoint at the entrance, and Guy Fawkes has been hired to stand guard. To make him look more dangerous, he wears a beret. However there's no-one to check, so Guy Fawkes is bored and eats a mandarin.
