碍 = 㝵 + 石 : Albert Einstein (Ø) rubs a lamp in the airplane's bathroom (ai4) and to his surprise a genie (㝵) appears, asking for his wish. Albert recognizes his chance to put one over on the king and asks the genie to summon a large rock (石) to obstruct (碍) the royal toilet.

艾 = 乂 + 艹 : Albert Einstein (Ø) cut himself, so he wanted to treat his wound with wormwood (艾) and mugwort (艾) in the airplane's bathroom (ai4).
