I'm with Lily. I love tangfastics and will carry on eating them even after it feels like they have stripped the lining from the roof of my mouth. I don't like Pringles. (The thought of them turns my stomach after watching one of those 'How do they do it?' programmes which showed how they made a potato-ey slurry first, then made the Pringles out of them.) I can't open a packet of rich tea finger biscuits without eating nearly all of them.
