讲

讲 = 井 + 讠 : Inside of the anglepod Joan of Arc finds and advertising column next to a well. The advertising column says that if a coin is thrown into the well, it will state a wise and helpful truth. Joan of Arc does so and the well speaks: "it is not wise to throw coins into a well".

井 = 二 + 丿 + 丨 : Joan of Arc (ji) is digging a well (井) inside the engine ((e)ng3). At first she was doing it by hand, but then she hooked up a capacitor (二) to a banana (丿) and a dinosaur bone (丨), which dig for her using the electrical energy.

Mnemonic symbol: this character looks like a big "i" (like in information), and I'll represent it by an advertising column. Maud Younger (y) gives a speech (讠) standing on top of an advertising column (讠) in the anthill's kitchen (an2).
