We had some crisps once that came in a big tube, I couldn't stop eating them, you'd have one then and put the lid on. Seconds later, you'd open the tube and eat a couple more. That would go on until the tube was exhausted. My girlfriend opened a tube and I said while she was doing it, "don't release, you'll never cease!"
I suggested it to their marketing team, but they said they were going with something else they already thought of. I still think that they ripped me off though.
