Oh lordy, thanks to Chris Rea's rampant use of the TURDIS...
Oi, I have a copyright on that word...!
My sister was up with her Border Terrier one time and we were heading out to walk him round Todmorden park. She grabbed 3 poo bags. Being the cautious type, I grabbed 2 more. She said that they were not needed because he had never needed more than 3 in one walk. 30 minutes later he had used up all 5! I nicknamed him
THE TURDIS there and then - not only was he bigger on the inside than the outside, but that space was full of crap!
