Water World: Saturn's moon Enceladus and the rings. Although both Enceladus and the ring particles are made up largely of water ice, they are very different. The small ring particles are too tiny to retain internal heat and have no way to get warm, so they are frozen and geologically dead. Enceladus, on the other hand, is subject to forces that heat its interior to this very day. This results in its famous south polar water jets--which are just visible here above the moon’s dark, southern limb--along with a sub-surface ocean. Details:http://go.nasa.gov/1l2KDpF

Zennnnnnnnnnnnn....
In case you still think you are the center of the universe.....
Here is Earth from 900 million miles away, from the vantage point of the rings of Saturn.
Image via the Cassini spacecraft, which has been orbiting Saturn since 2004.
This image was acquired by Cassini on July 19, 2013. From Earthsky.

Why There's No Fly Fishing On Saturn
Click on photo for full size image.
This massive storm, five times larger than any previously observed storm, has wrapped completely around the northern hemisphere of Saturn, covering 1.5 billion square miles, many times more than the surface of Earth.
Radio signals of lightning strikes record 10 strikes per second, but that's the maximum number per second the equipment is capable of recording, so there are likely many more strikes occurring.
I'm pretty sure I'd leave the float tube in the shed and stay home.
