Little light-hearted one-shot. There had been some sort of file error before where it showed the wrong story but I've fixed it now. Enjoy!

The Doctor opened the door to 221B Baker Street with a flourish from his Sonic Screwdriver. Standing in the doorway was John Watson, getting in coat on. He smiled broadly at the Doctor, and then went over to Mrs Hudson's to tell her the Doctor was there. Mrs Hudson appeared in the hallway, and gave the Doctor a warm hug.

"Aww. It's nice to see you again. Have you been taking care of that wife of yours?"

"What, River? She can take care of herself! But, yes, I did take her out to see the Fourth Tower of Swaying Grass."

"Did she enjoy it?"

"Yes. It was amazing. You should have come with us to see it!"

"That's nice of you, but really, I couldn't. I've got my own boys here to look after." She said, putting an arm around John and giving him a motherly look.

"Speaking about my boys, where's Sherlock?"

"Right here, Mrs Hudson!" Sherlock called, descending the steps and joining them in the now over-crowded hallway. He raised an eyebrow at the Doctor, a smirk forming on his face.

"What?" the Doctor asked in mock offence.

"That thing on your head. It looks ridiculous."

The Doctor opened his mouth in shock, his mouth making a 'o' shape. He furrowed his eyes, and raised his voice slightly.

"I'll have you know, this is a fez. Fezzes are cool."

John decided to join the conversation, and poke fun at the Doctor's alarming fashion sense. "Ahem, no it isn't."

The Doctor looked at him in horror. "How dare you!"

At that moment, Mrs Hudson decided to stop the argument from getting out of hand. "Now then boys, that's enough! John, Sherlock, when will you be back?"

The Doctor decided to answer for them. "Oh, I don't know. I'll try to get them back as soon as possible, I promise, Mrs H. But you know what the TARDIS is like, not incredibly accurate, but I'm sure I can get them back within a week or two."

Sherlock raised another perfectly arched eyebrow at this. "Yes, we all know how accurate your TARDIS is. Could you just remind me how far Moscow is from London?"

"Yes, well, that wasn't my best day… But anyway!" he said, clapping his hands together with a bit too much enthusiasm. "You two, come on, we've got a mystery to solve!"

Sherlock and John followed the Doctor into the TARDIS, which the Doctor had parked just around the corner. He opened the doors, and beckoned them inside.

"Come on, come on, we haven't got all day!"

"Um… Doctor, it's a time machine. We have all the time in the world" John said.

"Yes alright, alright smarty-pants."

Sherlock frowned. "I thought I was the clever one."

John smiled at him, his eyebrows raised. "No, you're the insulting one."

"You only say that because you recognise my superiority." Sherlock said, his sharp words slicing through the air.

"Ha! As if. And that proves my point. You are the insulting one."

Sherlock grumbled something under his breath, but John wasn't listening.

"So, Doctor. What do you have in store for us this time?"

"Oh, I don't know, how about Tu-eleva, 3872?"
