As humans, we know how much of a struggle it can be to twist open the occasional bottle or jar. It leaves us thinking things like, "What kind of sick twisted person human-proofed this container?"
But then we get the best feeling during that one victorious moment when we hear the seal break.
Meme the Border Collie knows that exact feeling. (She probably got it when she twisted the lid off of her "dog-proof" container...)
