Why Stonehenge was never finished

Thanks to Merlin and the Stonehenge News for this one.  I have argued on this site many times that Stonehenge was never finished, and that the builders walked away from the site in disgust for some reason or other.....

Well, now we have confirmation for that.  Click to enlarge the picture above.  Clearly, the giants employed by Merlin the magician (in an earlier incarnation, long long ago) were too stupid to be able to read the Ikea instructions!
