Here, Sherlock! Here, boy! Dammit! I thought he'd finally learned to come when I whistled.

Sherlock coming when you whistle? Oh, like that’s going to happen. (Okay, maybe in the fanfic…) However, I’m certain there are a great many fangirls (and boys) who’d be more than happy to respond, John.

To paraphrase Lauren Bacall, ” You know how to whistle,don’t you, John? You just put your lips together…and blow.”

Okay, I’m going to go have a little lie down now.
