John and Sherlock play MapCrunch:

John: How am I supposed to get to the airport from here? I'm in the middle of nowhere!
Sherlock: Look for the clues, John.
John: Clues? What clues? I'M IN A FIELD.
Sherlock: Do you need me to point out the obvious? There are a lot of things you can deduce from your surroundings.
John: Oh, come on. You're telling me you can deduce my location from the bloody grass pigmentation or something?
Sherlock: Don't be so stupid. Look, John. /Really/ look.
John: Forget it. I'm going to make some tea.
*John goes off into the kitchen.*
*Sherlock quickly grabs the laptop, and un-hides John's location. He then Googles directions to the nearest airport, before placing the laptop back in its prior position.*
*5 minutes later, John returns and sees Sherlock sitting reading a newspaper.*
John: Given up, have we? I told you it's impossible to know where you are.
Sherlock: Follow the road north for approximately 7.5 miles, before you come to a crossroad. Take the left turning for another 9, and then you will reach the outskirts of a large town. I trust you won't find it too hard to find the airport from there.
John: ... *Follows instructions.* B-but.. How did you get that from a field?!
Sherlock: I told you, John. You people just don't /see/.
John: Well, colour me impressed. *Laughs in disbelief* You were right. The signs to the airport are right here.
Sherlock: What did I tell you? *Smirks*
John: Alright, no need to rub it in. I still don't understand h- Hang on. Did you just /Google/ my location? *Checks history* YOU DID. You cheating liar, Sherlock Holmes!
Sherlock: *Lifts newspaper up to cover face* I don't know what you're talking about.
