正

Willy Walrus (w) and the stick figure (正) have been riding a carousel in front of the airplane (ai1) for too long. As they get off they sway (歪) a lot and aren't able to walk on a straight line anymore. They didn't see that there was a forbidden-sign (歪) hanging on the carousel because it's going way too fast.

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.

止
:
Mnemonic symbol: a stick-figure with straight lines. James II of England (zh) really has to use the engine's bathroom ((e)ng4), but there's a stick-figure (正) blocking the stalls with a barrier (止). The stick-figure measures with a flute (一) whether James is tall enough to go. James stands very straight (正) to make himself as tall as possible.
