Donna and the Doctor were preparing for Christmas. So was just about everyone in Chiswick. The Doctor took Donna home on Christmas Eve to see her Mum and Wilfred.

"Chiswick!" he announced spinning around in a circle.

Donna smiled at him, "Great. Anything we ought to do for you before we go and have an Earthy Christmas, you know, like some ancient Time Lord tradition?"

The Doctor shook his head, then paused, "Although…"

"Go on Doctor, what is it?"

"Adaregame," the Doctor muttered

"Beg yours?"

"A dare game!" the Doctor shouted.

"A dare game?" Captain Jack chose that moment to walk into the console room.

"A dare game?" Donna looked interested.

"Yeah," the Doctor nodded enthusiastically. "Everyone gets one dare and by midnight on Christmas they have to have completed it or they have to do something horrible."

"Ok!" Jack agreed very quickly, shooting an evil looking glare at the Doctor.

"You're on," Donna smiled sweetly at the captain.

"Neat," the Doctor smiled broadly at everyone, unaware of what he had just started.

"Ok," Jack said. "How do we play?"

"Just dare each other, anyone got a dare yet?"

Donna bit her lip and Jack began laughing so hard he couldn't speak.

"Oh," the Doctor grinned. "Alright then, if you can't think of anything, I guess I'll go first. Donna?"

Donna looked up at the Doctor with wide eyes and tilted her head, "Yeah?"

"I dare you…" he grinned manically. "I dare you to sing as many Christmas songs as you can, but" he held up a finger. "They all have to have something to do with what we've done the times you've been in the TARDIS."

Donna grinned, "Should I start now?"

"No, you've got to wait until everyone else has their dares too," the Doctor told her in a moaning voice.

Donna poked her tongue out at him, "Don't use that tone of voice with me mister."

"You sound like your mother," Jack told her.

"Thanks," Donna replied sarcastically.

"Please don't turn into your mum Donna," the Doctor said. "Just one of her is enough."

"Fine, anyway, I have a dare for you Jack…"

Authors note: Thanks for reading all the way to the end. I know Christmas is still a while away, but it's already haunting the shops, which is where I came up with the idea for this story. There is another story for why Jack is there, but it is lost on my computer, I'll post it as soon as I find it.

Penny for the story: Please Review, and while you're at it could you help me think of a dare for Jack and the Doctor.

Disclaimer: Unfortunately all I have is my overly watched DVDs and an ood action figure. And lots of books and… I could go on, but you'd get bored.
