Crocodile Song
(source: "Sing A Song For Sixes", Girl Guides of Canada, 1975)

Oh, she sailed away
On a fine and sunny day
On the back of a crocodile.
You see said she,
He's as tame as tame can be,
I'll ride him down the Nile.

The crock winked his eye
As the lady waved goodbye,
Wearing a great big smile.
But at the end of the ride
The lady was inside
And the smile was on the crocodile!
