Why eagles fly...

A long, long time ago
in a special place where realists went to dream
two young cows met a young bald eagle
Wanna play, asked the eagle
How, replied one of the cows
I'll pretend to fly
and you pretend to moo
said the eagle
So the cow moo'd
and the eagle flew
And that is why today
you see cows grazing in fields
and eagles soaring high in the sky
