孝 = ⺹ + 子 : Mnemonic symbol: a mourning veil.

Xi Shi (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).

酉 = 兀 + 日 : The rooster and Maud Younger are taking part in a re-enactment in the outhouse. They re-enact former times by getting up with sunrise; the rooster stands on top of the sun and crows so that everybody gets up, and Maud Younger plays a traditional sihu fiddle.
