where have you been all my life (and when are you going back?)

"You're never going to convince me," John said, shrugging. "I'm sorry, Sherlock, but not even you are good enough to understand the random pranks that replicator likes to play on us." He ignored the way Sherlock rolled his eyes (he was a pro, by now, at that) and followed him around the corner from the Aurelia concourse to the main hallway.

They reached the lift and John hit the button to call it down, turning to face Sherlock with his arms crossed over his chest. "There's no way you're getting me to believe that ordering tea from the science lab replicator is putting the ratborgs off their food."

He didn't bother pointing out that if Sherlock were correct about his ability to affect the replicator's output, it was a surefire way to get him to go out of his way to order tea from it as often as possible. Anything that brought those things closer to the demise they deserved was a deed well done in John's book.
