不窮

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.

穷 = 力 + 穴 : Cupid (qu) exhausted (穷) his bank account and is very poor (穷). He has nowhere to go and nothing to do anymore. In the engine's kitchen ((e)ng2) he creates a big cave painting (穴) out of boredom. Idly he paints a big power button (力) wishing that upon hitting it, money would rain down on him.
