I know you all remember this one but sometimes it's good to refresh one's memory.
How doth the little crocodile....by Lewis Carrol
How doth the little crocodile
Improve his shining tail,
And pour the waters of the Nile
On every golden scale?
How cheerfully he seems to grin
How neatly spreads his claws,
And welcomes little fishes in,
With gently smiling jaws!
