The London Underground is an institution, and it's fair to say that each line has a distinct personality.

Of course, there are certain lines on the London Underground whose reputations precede them. And, not necessarily in a good way. You know who you are.

But, what if the Tube lines were people?

Do the Hammersmith, City and Circle Lines really hang out together? Do they like each other? What does everyone think about the Northern Line? What's the deal with the Piccadilly Line, too?

Well, wonder no more. A group of comedians have parodied each Tube line and the individual — and often irritating — traits that make each line unique.
