Knights Templars and the Grail

This is very funny:

Then he went outside and started drawing what he saw. There is a minaret which sits on top of many civilizations worth of building works. There is also an arch. Roger drew a line from the top of the minaret to the arch, then from the base of the arch back to the base of the building the minaret stood on and then back up to the top of the minaret. “A perfect triangle”, he announced in triumph. I hadn’t the heart to tell him that joining any three lines would give him a triangle and that the minaret was not crusader.
[...]
Roger had a lion and a triangle. A symbol of the crusaders and geometry, he was a happy man. Insane but happy.
[...]
Roger took me aside. “I have discovered that there are ancient tunnels under the Temple Mount. I was talking to a guy in the hotel bar who told me he could take me there. I am supposed to meet him here in ten minutes.” I pointed to a sign saying Tunnels tour, just above his head”.
