The center of the Toilet Paper roll is filled with Tooth Paste. I should mention that between basic needs, the fun of simply spinning it off the roll, making mummies, and doubling as dog chew toys, we use a bunch of toilet paper. Second to food, toilet paper is given the highest priority in this house. Rethining that, I might allow us to run out of food before I would ever dare to run out of toilet paper. To have the toilet paper roll flopping around on the holder like a flat tire on a car and simultaneously smelling bubble gum (flavor tooth paste like bubble gum and children brush more) was a little unexpected first thing in the morning. This is the joy of parenting and, no, tooth paste in the toilet paper was not in the manual.
