My brother gave me the address of today's Non Sequitur and I loved it!
The link I've used comes out really small. I'm not sure why. I had to enlarge the screen to see it clearly. Here's another link that is normal-sized, but I suspect it might only be available today.
I've realised that if you click on the second link above, you just have to click on the calendar there for 7th November 2010 and you get that particular joke.
