xkcd

Far too much of my day has been wasted on these cartoons but I keep clicking the 'next' button. I just love nerdy humor, I hope my fellow procrastinators enjoy!

I love XKCD. My favourite strip is: Gullible.
 
XKCD is great-- I think it's oldjones that uses a strip in his sig. Mind you some of the geek humour might be a little opaque (RMS as a superhero or little Johnny Tables).
