單非

单 = 丷 + 田 + 十 : In front of the anthill there are many, really a field of crosses because Don Quixote killed so many people on his crusades. Today is his judgement day: a mean crocodile reads the list of his victims to him, and Don Quixote is really 不好意思.

非 = 三 + 丿 + 丨 : Mnemonic symbol: a negative film (photography).

Frankenstein's monster (f) made an effort to photograph the Eiffel Tower (ei1), but now his negative (非) is a big mess. In front of the tower he set up a camera on a Cartesian coordinate system (三) as a tripod, and he attached a banana (丿) and a dinosaur bone (丨) 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.
