Here's one of the children's poem I know by heart.
The Toothless Tiger
by James Campbell
(To be recited out loud, with lips kept over your teeth, if you have any.)
I am a toothless tiger
I have a toothless grin
I catch my prey with clawless paws
And suck ’till they give in
James Campbell did (does?) "Comedy for Kids" shows. I saw him with my children about twenty years ago at the Edinburgh Fringe. More recently he writes children's books, but some CDs of his old shows can be found second-hand.
