Firstly, our heroine Mary gets up, gets washed, puts on make up, gets on a crowded Tube half asleep, gets a seat, then gets off and eventually appears in Canary Wharf Tube station.
But what train is she on first (which line &/or ideally - for real Tube experts - which stock)? Bear in mind there may have been some artistic licence with the trains that were used and it may not be a train or a line that actually goes through Canary Wharf. See if you can work it out from the screen grabs below or by watching the video:
Usual competition rules apply - one guess only per person in the comments below. In the event of more than one person guessing correctly (which I think is likely to happen - even if you make a wild guess - there's a good chance in getting the line correct), all the correct entries will undergo the Neil paperclip selection, so that we'll have only one winner. People who make more than one guess will be disqualified. Please leave your email address or your blog/website in the comments if you wish to enter. You have until Sunday 8th January 2006 23.59 GMT to make your guess.
Oh and the prize - a wonderful enamel "No Begging" London Underground fridge magnet - ideal for putting on filing cabinets too to tell colleagues they can't beg to get favours from you.
