據我所知

据 = 居 + 扌 : Zeus (ju) wants to use the toilet in the space station's bathroom (Ø4), but it is occupied (据) by a hermite crab (居) which states that the toilet is its new home and cannot be used anymore. Consequently Zeus seizes (据) the crab by using a toy claw (扌) with which he pulls the hermite crab out of the toilet.

我 = 戈 + 手 : I (我) find Willy Walrus (w) lying motionless in the observatory's living room (o3), and there's a dagger-axe (戈) sticking right in his chest. I (我) try to pull it out while wearing a baseball glove (手).

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).
