I think the video above is the perfect silly Sunday video. What better way to cure your hangover than listening to Jay Foreman sing the names of all 270 tube stations?
You can also watch some of his other videos:
Unfinished London episode 1: Answering the question 'Why does Mill Hill East exist?'
Unfinished London episode 3 (part 1): Answering the question 'Why does London have so many airports?'
Unfinished London episode 3 (part 2): Which doesn't really answer the any questions about the future of London's airports.
Now, you may have noticed I don't have a link to Unfinished London episode 2; that's because it's a video better suited to a Monday morning.
