Snappy Chewing Gum - Remember this? It's something you always used to find in the jokes section at the local sweetshop round our way... a Wrigley's Chewing Gum-shaped pack which, when you offered it to your unsuspecting victim and they took one, would snap (and hurt!).
Absolutely great to see an old favourite back where it belongs. Happy Snapping!
