Friday the 13th: Leftovers

As Friday the thirteenth drew to a close, I had some links left over:

• "A Brief History of Friday the 13th"
  Time (February 13, 2009)
• "The Thirteen Club"
  Boston University School of Theology
• "The Code of Hammurabi"
  The Constitution Society

What's the Code of Hammurabi doing there? Look for law #13. It's not there. At all.
