It might take you a second or two to work these out. But trust us, the tube nerd in your life will lap these up.
These exclusive Londonist t shirts, priced £17.99, make ideal Xmas presents, secret Santas and stocking fillers.
King's Cross station
It's an oldie but a goodie. King's Crustacean... King's Cross station... geddit?! Give this to the crabbiest person you know, and it'll still put a smile on their face.
Lambeth
Actually the real etymology of Lambeth isn't far off — it comes from 'landing place for lambs'. Still, this t shirt has a picture of a lamb in a bath. And you can't go far wrong with that.
Baker Street
Baker Street resident Sherlock Holmes would like this tasty number, we reckon. It'll make a sweet gift for one of your mates, too.
There are plenty of other London centric designs in the Londonist shop. Make someone very happy this Christmas.
