Frankenstein's monster made an effort to photograph the Eiffel Tower, but now his negative is a big mess. In front of the tower her set up a camera on a Cartesian coordinate system as a tripod, and he attached a banana and a dinosaur bone to the camera so that he can finely tune the angles. All was for naught as he now holds the messed up negative in his hands.

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.

I'll use a specific style as mnemonic symbol: 哥特式, gothic.
Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
