A friend of mine sent me this. I thought it was very cool.

 

Eternity in Measured Time 

On the Island of Thor there is a rock.
It’s a thousand miles high, and
It’s a thousand miles wide.
Once every million years,
A small bird comes to sharpen his beak.
When the rock is thus worn away,
One second of Eternity will have passed.

 

The only problem with it, of course, is that Eternity is even longer than that.
