Edit: This was mis-linked by me via myconfinedspace.com and my newsreader - I didn’t realize that things got cut off and munged up. In particular, the artist’s credits had been chopped off. NOT GOOD. The artist is Matthew Inman and the original image (actually, it’s a set of images, which is why I’m attributing it this way as I’m mobile and pushed for time, and will fix it up correctly later, hopefully) is available at The Oatmeal. Check it out and surf his site, there’s a TON of funny stuff there. My apologies to Matthew, and thanks to James for catching this and asking me to take some action on it.
I’ll hopefully get to fixing this up later in the day.
