Y4G Assembly GNU

Here are the words for GNU:

I'm a gnu  i'm a gnu
The g- nicest work of g- nature in the zoo
I'm a gnu how do you do?
You really ought to k-now w-ho's w-ho

I'm a gnu
Spelt GNU
I'm g-not a camel or a kangaroo
So let me introduce 
I'm g-neither man or moose
Oh g-no g-no g-no i'm a gnu

I'm a gnu a g-nother gnu
I wish I could g-nash my teeth at you
I'm a gnu how do you do?
You really ought to k-now w-ho's w-ho

I'm a gnu 
Spelt GNU
Call me Bison or Okapi and i'll sue
G-nor I am the least
Like that dreadful hartebeast

Oh g-no g-no g-no i'm a gnu!

By Pablo
