证实

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.

实 = 头 + 宀 : Sherlock Holmes welcomes professor Skull just inside the entrance of the space station. Professor Skull has not a complete head but only a skull, and a solid understanding of solid state physics. She really is an honest person and still wears her graduation cap.
