孝 = ⺹ + 子 : Mnemonic symbol: a mourning veil. Marie Curie (xi) was breeding an egg (子) in the aorta's bathroom (ao4), and she even put a crown (⺹) on it (the crown is on top of the egg: 孝), so much she loved her little prince. Unfortunately the egg died, and thus Marie Curie put on her mourning veil (孝).

疒 = 亠 + 广 : Napoleon started a war, and his first act is to parachute into the elevator's bathroom, wearing his military beret and all. He's lucky to have landed in the bathroom because unfortunately he's sick, with a colorful rash all about his skin and the urge to puke.
