Tophat is cheating since he's standing on the back of a turtle.
Turtles all the way down - Wikipedia, the free encyclopedia
A version appears in Stephen Hawking's 1988 book A Brief History of Time, which starts:
“ A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever," said the old lady. "But it's turtles all the way down!"
I now believe that the little old lady was our very own illustrious Tophat665...ever notice how fishy he acts?
