I remember jokes about going through the earth to the other side in China when I was a kid. I didn’t take into account getting burned up by the core but I figured at some point in the middle the gravity would shift. Like the opposite of working your way to the center of a merry-go-round. Do any playgrounds still have those?
This particular strip is an amazing artistic feat as absolutely no characters from the comic actually appear in it. You are impressed are you not?
