I worked with a fellow who told me he had gone to a logic conference. One group there purposed the earth was on a turtles back. When questioned about what was supporting the turtle.
The response was: "It is turtles all the way down"
One of the truly great answers to a deep question.
If Big Kev is watching the list, he could correct my version of the story and my English.
