AN: Okay, so maybe I'm slightly addicted to Sherlock. I can't stop WRITING!

Disclaimer: I don't own Sherlock (*grumbles*)

"Sherlock," John began, as his flatmate collapsed gracefully on to the sofa, finally beginning to show the strain of five days without sleep or food.

"Hmm?"

Sherlock looked up at him, with the oh-so-familiar "99% of the population are totally pointless and stupid" look on his face.

"John, nothing is impossible." He said firmly.

"But-"

"Nothing is impossible. Things are difficult, or unlikely, or both, but never impossible."

"I will prove you wrong, you know..."

"You do that..."
