Great eds have little eds upon their backs to bite 'em,
And little eds have lesser eds, and so ad infinitum.
And the great eds themselves, in turn, have Admin eds to go on;
While these again have greater still, and greater still, and so on.

Ice eggs, also known as ice balls, are a rare phenomenon caused by a process in which small pieces of sea ice in open water are rolled over by wind and currents in freezing conditions and grow into spheroid pieces of ice. They sometimes collect into heaps of balls on beaches where they pack together in striking patterns. The gentle churn of water, blown by a suitably stiff breeze, makes concentric layers of ice form on a seed particle that then grows into the floating ball as it rolls through the freezing currents. This formation of ice eggs was photographed in 2014 on Stroomi Beach in Tallinn, Estonia. The temperature was around −20 to −15 °C (−4 to 5 °F), and the diameter of each ball around 5 to 10 centimetres (2 to 4 in).
