The Doctor flung open the doors to the TARDIS, chatting away . ' Mooston .Sto, the biggest city in space . There are cathedrals , churches , ducks that go woof .. he continued .

' And a cow .. ' he stopped talking . A jersey cow mooing was blocking his TARDIS.

' Ohhh , Mooston . ' ' Get it Donna ? ' he turned to Donna who was standing behind him. " Moo ? Cow? 'she just stood there shaking her head. Sometimes those jokes of his were just really bad .

Meanwhile , the Doctor started talking to the cow. ' Now then , cow , where did you come from ? ' he wondered . ' Oh , I'm sorry, Daisy '. He apologised .

' Excuse me, Doctor ? 'Donna asked.' What ARE you doing? '

Oh, didn't I tell you ? He turned around , a cheeky smile on his face. ' I speak cow' .

They started following the cow across a field that was covered with sunflowers . It smelt like spring in the air, however being in the TARDIS it felt like it was a different season each time they landed somewhere new . The Doctor kept answering each time the cow mooed . ' Oh is that right ? He cooed . ' A house? A white house ? Do you belong to the President ? ' He looked over at Donna as she walked beside him his eyebrows raised , smirking. He was wearing his usual brown suit with white converse .

' Doctor ' , she told him . He wasn't paying attention , now mooing back at the cow .

' Doctor ', she repeated. He still wasn't paying attention .

DOCTOR LOOK ! , raising her voice . He looked around to where she was pointing, towards a wire fence .

' Another cow' he stated , now looking confused . His face lit up . ' I've always wanted to say that line' . Donna just groaned.

They were now following two jersey cows across the field . The sun was beating down on them . It was a hot day . As they walked , he was having a conversation with the two cows . Mooing each time they mooed . Donna thought he was enjoying himself.

' Okay ', he was saying . ' These cows, Daisy and Daffodil belong to the same house . But where ? ' Looking around, he put his glasses on. ' Oh I can't think ' he complained, smacking his forehead. ' These cows won't stop talking'

' Well don't talk to them ' she suggested .

' Get a bit of perspective Donna ' he responded , still watching the cows . ' These cows belong somewhere , and we have to get them home '

' Yeah , maybe in a milking shed 'she uttered. The Doctor stopped walking and turned to her.

'You and your sass' he observed, raising an eyebrow. Donna chose to ignore him.

After about half an hour, where the field started to thin out from sunflowers , they noticed that white house the cows supposedly were telling the Doctor about . ' Oh that's your home ' he cooed to them . ' And there is someone outside ', noticing a short man at the picket fence , with small ears poking out of his blue cap .

The Doctor walked up towards him. ' Hello ,' he called . ' I'm the Doctor , this is Donna ,and we are returning your cows ' he was beaming at the man.

The man stood up , a red bucket in his hand . He noticed the cows that were now grazing on the grass nearby, and raised a small hand in greeting. However , he waited until they arrived before speaking .

' Why thankyou Doctor and Donna ' . He had a squeaky voice. 'I was wondering what happened to them . Its time for their milking'.He pointed to another white building, made out of wood with a red roof. ' In that milking shed'

As they walked off back to the TARDIS, Donna glanced over at the Doctor . He was quiet, kicking his feet on the grass as he walked, probably missing the fun they just had. It was evident, as he was pouting.

'Doctor' she uttered, breaking the silence.

He looked over at Donna, who was smirking and was trying to choke back a laugh , ' Told you they belonged in a milking shed'.
