A Jack Russell named Sid has learned to play catch with himself.
In a video filmed in London, owner Roland Muldoon encourages Sid to play alone. The dog can be seen rolling a tennis ball down some steps then running to the bottom to catch it. He does it over and over again.
In less than a week, the YouTube video has racked up over 250,000 hits.
