a/n: I was bored so i just thought i'd have a go at this. it's my first attempt at a crossover so i'm not sure how it will turn out.

The Doctor was happily bouncing around the TARDIS again. He had just managed to prevent an intergalactic war and so was feeling VERY pleased with himself. He just needed a quick pit stop in Cardiff to boost the power levels, and then he could be off again.

As the TARDIS materialised on top of the rift, the Doctor noticed that the screen on the control panel showed that he was in the 21st century, 2010 to be exact. Smiling, the Doctor thought that he just might pay a visit to Jack and his gang while he was waiting.

Just then, there was a decidedly polite rap on the door. Confused, not thinking to just check his screen to see who was out there, the Doctor went and opened it. There was a young policeman, who looked like he had just graduated from the academy, standing imperiously outside.

"I'm afraid you're going to have to move this..." he paused, looking up, "Police Public Call Box. You are in violation of the law leaving this object as an obstruction in a public place."

The Doctor just stood there staring at the man; for once he was utterly speechless. Humans could only notice the TARDIS if they were looking for it. This young man must have been searching for some sort of violation to report to his superiors, or he would have walked right by it like everyone else in the square this morning.

The Doctor's mind realised this in less than one tenth of a second, but he still stood there staring for at least another five whole ones. Then he exploded.

"WHAT?"

The poor man jumped backwards, surprised. The Doctor ranted on.

"Firstly, this is ridiculous!

Secondly, this is NOT an object, it is a vehicle!"

The police officer, who seemed to have regained his composure, simply stated;

"Well then, I'm going to have to give you a parking ticket, sir."

The Doctor was truly horrified, his mouth falling open. This insignificant human intended to give him, the last time lord in the universe, a Parking Ticket! The Doctor's mouth opened and closed, opened and closed. He was doing a perfect imitation of a fish!

A small part of his mind registered that, had anybody else been paying attention, they probably would have been in tears of laughter. The Doctor himself probably would have been as well had he not been facing a fine.

Just then, the Doctor was saved. None other than Captain Jack Harkness appeared, flashed his Torchwood identification card, and sent the offending police officer away.

Mutely, the Doctor gestured for Jack to join him in the TARDIS. By the time they were both in, the Doctor seemed to be getting over his shock. They both dissolved into uncontrollable laughter.

"Jack, I don't think I've ever been so glad to see you!" the Doctor exclaimed.

"I didn't think you were ever glad to see me, but good to see you to." Jack replied, his face spreading into a huge grin.

Suddenly, the TARDIS lurched to the side and the Doctor and Jack were thrown violently to the floor.

The whirring of the TARDIS started up and she dematerialised of her own accord.

Jack looked at the Doctor over the mushroom shaped control panel;

"Looks like we're off on another adventure then, you're stuck with me."

The Doctor couldn't honestly say that he was disappointed!
