But apparently it DOES grow in the dryer! Wish my dryer always looked like this when I opened it! When the kids were little, I always told them that I got to keep anything that came out of their pockets, hoping that they would empty them of their treasures before they were washed. Alas, I still found rocks and sticks, discarded grasshoppers, and plenty of dirt, not to mention the occasional cast off calf ear tip or two if we happened to be branding.
By the time they were 10, they were doing their own laundry. :)
