Not sure how many of you have seen this but with the Darts being on the BBC today and given I'm a secret darts fan suffering from Darts Fever here is a classic Not The Nine o Clock News joke.
Sadly the BBC only has rights to the BDO matches so we don't get to watch the legend that is Phil 'The Power' Taylor who plays in the PDC. Currently 1st round of the World Professional Championships so if you don't like darts you're buggered for a while on the BBC.
I've seen Veterinarians discuss that this is an epileptic shock. But then again the person that added this has several movies of the dog doing it, and loads of people that report of their dogs doing this, so I'm not 100% convinced what to believe.
