Explanation
Ponytail resumes her role as a cosmic home inspector.
She asks Cueball when the last time he flipped the tectonic plates, because they look heavily eroded. This may be an allusion to the practice of turning mattresses over every few months. This was common until the 20th century, to even out the wear and tear, and prevent permanent body impressions. When modern box springs became common, the practice became unnecessary.
Flipping mattresses only makes sense because both sides are similar to each other, but the "underside" of a plate is nothing like the surface. The current side that Cueball and Ponytail are standing on is the outermost layer of the crust. However, the "underside" of the plate reaches until the solid layer of the mantle, whose temperature can reach over 1000 °C. As Cueball points out, if you could flip a continent over, the new surface would be molten rock, not a surface suitable for life. Ponytail thinks the warmth would be soothing, and that walking on it would exfoliate your feet, but at hundreds of degrees, it would do far more damage than just removing dead skin.[citation needed]
The title text expands on this joke, saying that it would "exfoliate" just about everything on the surface (which would somehow have to stay in place while the plate below it is flipped).
Transcript

- Cueball: ...Never?
- Ponytail: Wow. Explains the eons of weathering, debris basins, and ... is this isostatic depression?

- Cueball: But I like this landscape!
- Ponytail: Just think how warm and fresh the other side will feel.
- Cueball: A sea of molten rock?
- Ponytail: Good for the feet. Helps exfoliate.
