No Sense is Nonsense

There was a Gnu
In a zoo
Who had flue
And he was so sick
He could no more pick
The nuts people threw

I went to a shop
To buy some crop
But there was none
So I came back
With a brown sack
Full of bun

My pet bear
Was such a dear
That he would not
Without a cot
Go to sleep
Like a perfect creep

If in the sky
The birds do fly
Then they must have flew
In the skew
And will be flying
In the skying

Mr Moo of Mozambik
Was a bit eccentric
He would have
One dozen crab
For his lunch
Which he would munch
And then complain
They taste like toothpick
