界碑

界 = 介 + 田 : Joan of Arc wants to leave this world and sets up a rocket launch field in the elevator's bathroom. The field looks like a normal crop field, except that there's a rocket in the middle and that the Joan of Arc marked the boundary with white and red tape.

碑 = 卑 + 石 : Beelzebub (b) finds it annoying that everyone finds the Eiffel Tower so impressive. He moves a rock (石) from the Alps (卑) in front of it (ei1) and creates a monument (碑) much larger than the tower to remind everyone that the Alps are much more impressive.
