密教

密 = 宀 + 必 + 山 : Marilyn Monroe (mi) is secretly (密) making out with her secretary (密) Khubilai Khan (必). Because it has to be a secret (密), they meet in the space station's bathroom (Ø4) and hide under a huge graduation cap (宀). Just to be sure Khubilai Khan has two forks (山) in his hands to attack anyone who might enter and see them.

教 = 孝 + 攵 : Joan of Arc joined an apocalyptic religious sect that taught her to dig her own grave. Wearing a mourning veil, she breaks the floor of the aorta's bathroom open using a sledgehammer.
