Most dogs when you throw a stick they run off, pick it up, and bring it back. It's simple. job done. Right? Not so it seems, photographer Andrew Knapp's border collie Momo has a different way of playing that game.
When Knapp throws a stick Momo runs off and hides, it became such a regular occurrence that Knapp began photographing him stealthily concealing himself in the scenery.
Knapp would often give the photos to his family, encouraging them to see if they could spot Momo in the picture.
He then began uploading them online asking people to find momo in the images and, it being the internet, people loved it. Of course they would. Forget 'Where's Waldo', who wants to spot a nerdy looking guy with big glasses and terrible taste in clothing when you've got a four-legged fury dog to entertain your surveillance skills.
It proved so popular that last year Knapp even brought out a book Find Momo Coast to Coast, where Knapp and Momo took off in a VW camper van on a fun journey across the United States and Knapp took photos of his black and white dog hiding from Las Vegas to New York.
You might think how much fun can finding a dog in a photo be, but once you start looking for Momo, and he's not easy to spot, you begin to want to find him in every damn picture.
Well it's that or you actually have to do some work today. What's it going to be?
