My Casius Clay, thus, Mohammed Ali version - on my bedroom wall.

I float like a butterfly,
I sting like a bee.

I chop and change,
And duck and dive,
All the time in my mind you see.

Old yellow Nick, can't work out what his his brain can't conceive,
He just can't get me in my mind you see.

He thinks he knows me but I know he don't,
He thinks he'll get me but I know he won't.

Now the price they'll pay is with their lives you see,
That'll teach them for picking on someone small like me.

I told you once evil realm, I told you twice you suckers.

I Am the Greatest !
