"The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain any more so it eats it. (It's rather like getting tenure.)" --Daniel Dennett, in Consciousness Explained (1991), p. 177.
Dennett credits the tenure analogy to Rodolfo Llinas; It can be found in Llinas' article, "'Mindness' as a Functional State of the Brain," in Mindwaves, C. Blakemore and S. Greenfield, Eds. (1987), p. 341. The Dennett quote gained wide circulation after an NPR piece by Andrei Codrescu, which aired in 1996. The piece itself isn't in the NPR audio archives, which apparently started shortly after it aired, but the event is memorialized here.

Here are some simple calculational rules for the Dates of Easter, Rosh Hashanah, and Passover (thanks to John Horton Conway, of Princeton University. These rules are based on his book with Berlekamp and Guy, Winning Ways.)
