Notes:

Here I come, rougher than Knuckles
The best of them, tougher than Knuckles
You can call me Knuckles, unlike Knuckles I don't chuckle
I'd rather flex my Knuckles
I'm hard as Knuckles, it ain't hard to chuckle
I break 'em down whether they're Knuckles or Knuckles
Unlike Knuckles I'm independent since my first chuckle
First Knuckles, feel the Knuckles, than the Knuckle chuckle
Oh no
