正劇

正 = 一 + 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.

剧 = 刂 + 居 : Zeus (ju) is making a big, serious (剧) drama (剧) in the space station's bathroom (Ø4). A hermite crab (居) decided to move in in the toilet, but Zeus has to urgently use it. Zeus threatens that if the hermite crab doesn't get out voluntarily, he will force it out with a kitchen knife (刂).
