取證

取 = 又 + 耳 : Mnemonic symbol when used as component in other characters: a bloody ear.

When Mike Tyson was fighting against Evander Holyfield, he did not only beat Evander's ear (耳) with his boxing glove (又). Imagine this fight in the space station (Ø3) with cupid (qu) as referee fetching (取) a bloody ear flying through the space station.

证 = 正 + 讠 : James II of England (zh) is not allowed to stay any longer in the engine, so in the bathroom ((e)ng4) he forges a visa (证) so he can stay. On an advertising column (讠) he scribbles his fake visa, but (like me) he sucks at drawing, so he is only able to draw a stick figure (正) where his photo should go.
