The Tree in the Quad
("To be or not to be?" - A very important question!)

There once was a man who said: "God
Must think it exceedingliy odd
If he finds that this tree continues to be
when there's no one about in the quad.

Dear Sir, your astonishment's odd!
I'm always about in the quad
And that's why the tree will continue to be
Since observed by yours faithfully - God!

The fast Lady

There was a young lady named Bright
Whose speed was much faster than light.
She set out one day in a relative way
And returned on the previous night.
