OK, I'm on the tube - that's the London Underground System for those who don't speak 'London'. I'd brought a good book and my i-pod (love my i-pod - nearly 9,000 songs on shuffle!) so I had plenty to keep me busy. But still my mind wandered.
Take a look at this map and find square D3.
Have a good look.
Notice anything funny about the names of the stations? Anything inconsistent?
I'll tell you what I saw - next to each other on the Piccadilly Line there are two stations: Barons Court and Earl's Court.
Now do you notice any inconsistency?
How's this - "Earl's Court" has an apostrophe but "Barons Court" doesn't. What's going on there?
OK, so the one court belongs to an Earl, or did when they named it, maybe. Didn't the other court ever belong to a Baron? If not, who owned it? And why were there so many Barons there that the place had to be named after them?
It's a mystery that addled my tiny brain all the way home.
By the way, if you're into the design of the tube map, like I am, you might like some of these:
The 1932 map.
The 1956 map.

That's a real Circle Line.

Finally, my favourite:
Watch the trains!
Oh wait, nearly forgot this one, which I actually used to do when I was little. How sad is that?
