The moon is the same as your torso. Because you’re so FAT! AHHAHAHAHAHA. I’m sorry, that was mean. But really, if your torso was as big as the moon, you’d have one large torso, y’know?
Your torso got so big because of all the doughnuts (どう) you ate. You ate so many doughnuts that your torso got to be the size of the moon and then you floated away into space with your own gravitational pull and everything. Doughnuts are dangerous things.
