守正不阿

守 = 宀 + 寸 : Sherlock Holmes just graduated from police school and stands guard in the outhouse. Still wearing his graduation cap and carrying a huge shield, he's protecting the outhouse's art. The visitors are a bit afraid of him, so he thumbs up to show them that there's no danger from him.

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.

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.

阿 = 可 + 阝 : Mnemonic symbol: 阿姨 (a1yi2), "auntie"

阿 = 可 + 阝 : Auntie, Albert Einstein and the Pope are having a contest in front of the ashram: Who can sit longer on a bed of nails? The Pope secretly calls God's power and just hovers a little over the bed of nails. Albert Einstein calculates exactly how he has to place his body to not excert too much force on any body part. Auntie just sits down on the bed of nails, and wins in the end.
