Random Quote

I haven't heard anyone saying that she's blackmailing anyone. I think she just wants to see if our freedom of religious expression is really protected or is the court supposed to cater to the whims of the masses who want to shop and open stores on Sunday or any other religious holiday.

Now that the door is opened to contemplating rotating cats, I think we should look at organisms that are even better at the spinning routine.

Wow! The Hoop Snake people were right! http://en.wikipedia.org/wiki/Hoop_snake

BTW, having rolled down a high, grassy hill myself, (not in the manner illustrated) I wonder how the salamanders cope with the high level of dizziness this causes. It would be educational to follow them a bit longer and see if they emulate Hobbes, just out of the dryer. http://www.gocomics.com/calvinandhobbes/2012/01/21

Drunken salamanders could be very funny.

And then of course there is the Gloucester Cheese Rolling Event. . It keeps the local NHS orthopaedic unit in practice....

I saw similar behaviour in gorillas at the Virungas. The forest is very steep and covered by dense layers of ferns, and some of the gorillas simply roll down; they are very spherical when seated.

One of them were looking back to me and then suddenly made a 180º turn and rolled down into the brush. His gracefulness suprised me just at the moment I fell on the same hidden root. He was not doing ninja movements, he fell.

Check out the Pebble toad (Oreophrynella niger). This toad lives atop tepui in the Guiana highlands of south america. When threatened, often by tarantulas, it rolls into ball, and typically being on an incline, rolls away under gravity like a loose pebble.

What is a dogie, anyhow. Any chance of seeing one of them roll?
