Martha had got a day off from the shop so the Doctor thought it would be good if they took a trip to the countryside to meet with Kathy to get her to write the letter to Sally. Plus, it was a good opportunity for the Doctor to test out his timey wimey detector that he had just finished building. When they arrived, it turned out that Kathy wasn't there; she was on holiday with her family. The Doctor and Martha were a little disappointed but then decided that it wasn't all bad because it would give them a break from being stuck in their tiny flat.
Suddenly, the timey wimey detector let out a loud ding. The Doctor took one look at Martha with a wide smile on his face and set off towards the 'stuff.' Martha followed close behind, also smiling. After all this time travelling with the Doctor, she still got a thrill every time they discovered something new.
The Doctor came to an abrupt halt and then spun round in a circle as he tried to detect where his machine was leading him. Martha watched what the Doctor was doing for a while until she noticed a chicken in her line of vision. When the timey wimey detector was pointed towards the chicken, the bird let out a loud cluck and started acting very weirdly. It was shaking violently and running around like, well, a headless chicken. The Doctor and Martha studied the chicken closely. It seemed to swell uncontrollably as a boiling sound reached their ears. Suddenly there was a loud pop. The Doctor instinctively placed his detector in front of his face while Martha barely had time to cover her face with her hands. After a few seconds, they risked a look. The chicken had disappeared; well to be more precise, it had exploded. They were both covered in gunk, there were feathers lying all over the ground and an egg lay on the ground.
The Doctor, being ever curious, edged towards the egg. He bent to pick up and let out a small yelp as it was hot to the touch. "Oh, brilliant," he gushed, "thermal molecular gastronomy of a gallus domesticus. I mean, it's not perfected because it kills the chicken. I imagine it's a combination of shock and boiling water in their body. Oh, and the fact they explode. But, Martha, my timey wimey detector can also boil eggs."
"Great," Martha said sarcastically as she spat some feathers out of her mouth.
The Doctor was about to say more as the timey wimey detector let out another ding. He looked around eagerly for the source and spotted another chicken in the distance. Martha groaned as she noticed that the chicken was shaking violently. She pulled on the Doctor's arm to get his attention. His mouth dropped open slightly as he began to realise what was going to happen.
"Don't just stand there," Martha yelled. "Run. I'm not being covered in exploding chicken again."
They began to run but they didn't get very far before they heard another loud pop.
"I'd say that was 30 paces. 30 paces away and it still manages to boil an egg," the Doctor said, full of wonder.
He stopped when he spotted Martha glaring dirtily at him. She could feel the stickiness of the gunk on her body and was in desperate need of a shower so she was not amused about the way the day's events were turning out.
If looks could kill, the Doctor thought with a gulp, never mind regeneration. I'd be worse off than those chickens.
Author's Note: Thanks, Google, for helping me find the scientific terms to make the Doctor seem more in character. The phrase I used is really just a geeky way of saying 'boiling an egg.'
