When we go out walking, we sometimes drop something when Penny's not looking, and then act as if we're distressed, saying, 'Where is it?', and Penny races back to show us where the 'lost' article is.
I thought of this trick as I watched the cute little KLM beagle racing around the airport to return lost items to passengers, and thought it was lovely.
After that, I had a look around the Net and discovered there's no such dog helping out in KLM's lost-and-found department. It's just a publicity stunt.
But I still loved the clip. I've watched it three times already.
