This is just the coolest thing - it's a super high resolution online image of the Last Supper. It's detailed and has all kinds of little tour-guide points to notice. So even if you don't happen to find yourself in Milan (and why not?), you can still stare yourself silly and learn a bit.
However. If you're like me, it will put you in mind of "the big arms thing" and then you will have "Dress to Kill" immovably stuck in your head.
And that will make you go look for the clip online (although you will only find the transcript).
And that will make you find the "Four Yorkshiremen" sketch, which you will then have to watch, because Eddie Izzard laughing makes you laugh, and Alan Rickman is the best deadpan there is.
And that, my friends, is how my train of thought works.
Now if you'll excuse me, I think Jesus has just come in.
