Ah, I finally found that quote I always wanted to use on such occasion: Foucault's Pendulum, Eco, 1988, pp.288, 289:

Amid all the nonsense there are some unimpeachable truths... I invite you to go and measure [an arbitrarily selected, but specific] kiosk. you will see that the length of the counter is one hundred and forty-nine centimeters - in other words, one hundred-billionth of the distance between the earth and the sun. The height at the rear, one hundred and seventy-six centimeters, divided by the width of the window, fifty-six centimeters, is 3.14. The height at the front is nineteen decimeters, equal, in other words, to the number of years of the Greek lunar cycle. The sum of the heights of the two front corners is one hundred and ninety times two plus one hundred and seventy-six times two, which equals seven hundred and thirty-two, the date of the victory at Poitiers. The thickness of the counter is 3.10 centimeters, and the width of the cornice of the window is 8.8 centimeters. Replacing the numbers before the decimals by the corresponding letters of the alphabet, we obtain C for ten and H for eight, or C10H8, which is the formula for naphthalene. ...With numbers you can do anything you like. Suppose I have the sacred number 9 and I want to get the number 1314, date of the execution of Jacques de Molay - a date dear to anyone who professes devotion to the Templar tradition of knighthood.

...Multiply nine by one hundred and forty-six, the fateful day of the destruction of Carthage. How did I arrive at this? I divided thirteen hundred and fourteen by two, by three, et cetera, until I found a satisfying date. I could also have divided thirteen hundred and fourteen by 6.28, the double of 3.14, and I would have got two hundred and nine. That is the year Attalus I, king of Pergamon, ascended the throne. You see? ...The universe is a great symphony of numerical correspondences... numbers and their symbolisms provide a path to special knowledge. But if the world, below and above, is a system of correspondences where tout se tient, it's natural for the [lottery] kiosk and the pyramid, both works of man, to reproduce in their structure, unconsciously, the harmonies of the cosmos.
