Sometimes you get a poem stuck in your head and end up repeating it as you walk along. This is one of those...
The world Is Flat
Columbus said the world is round?
Don't you believe a word of that.
For I've been down to the edge of the world,
Sat on the edge where the wild wind whirled,
peeked over the ledge where the blue smoke curls,
And I can tell you, boys and girls,
the world is FLAT!
By Shel Silverstein from Where The Sidewalk Ends
