The incredible worm

Into a brook dropped a worm on a hook. "Bless my soul!" said a trout with a yell. "What a marvellous treat - something tasty to eat. And I'm just getting peckish as well!" The worm said,"I'm tasty but don't be too hasty, To eat me would be a great blunder As a matter of fact I can dance, sing and act.

In a word - I'm an absolute wonder!"
