不知痛痒

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).

痛 = 甬 + 疒 : Tommy Turtle has a terrible disease. In engine's bathroom, he discovered by looking into a mirror that he has a very colorful rash. He also has a terrible headache, just as if someone were to let yongzhong bells ring right next to his head.

痒 = 疒 + 羊 : The sheep (羊) got a colorful rash (疒) in the anglepod (ang3) and is very itchy (痒). Maud Younger (y) has to scratch (痒) his itches at all times.
