This is just getting rediculous. It's like when you step in chewing gum, or even worse, dog poo, and it gets stuck on the bottom of your shib-shib and you can't get it off. No matter how hard you try; you rub your shib-shib on the ground, on the grass, on the edge of the street curb, or you get a stick and try to push it off. But it just doesn't want to go.
The solution: It's time to throw those shib-shib away!
