体 = 亻 + 本 : Rosa Luxemburg envies Mother Teresa's hot body. She asks her how she can be such a hottie even when lifting is not possible, like in the space station's zero gravity, and Mother Teresa answers that it's because of the roots she's eating.

育 = 亠 + 厶 + 月 : Yu the Great (yu) wants to rear (育) a fake nose (厶) she found in the space station's bathroom (Ø4), so she made a nest out of the moon (月), put the fake nose on top of it, covered the fake nose with a cozy beret (亠) and sits on top of the beret to keep the fake nose warm and rear it.

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.
