There are sites dedicated to them, but can you make up your own clever Chuck Norrisisms? Heres mine:
Chuck Norris doesn’t need to study, he just roundhouse kicks the books until they bleed the knowledge that he needs.
Your turn. 
That’s pretty similar to one from this site:

Chuck Norris doesn’t read books. He stares them down until he gets the information he wants.
Eh, guess I should have figured somebody would do one with books. Dang that Chuck Norris. 
One time Chuck Norris asked a kid what time it was. Unfortunately the poor kid was not wearing a watch and could not answer his question. In a rage, Chuck Norris roundhouse kicked him within an inch of his life screaming “if you ever again can’t answer a quesion I ask I will kick the CRAP out of you and everyone who has ever known you!” From that day the kid devoted his entire life researching the answer to every question just in case he were to ever meet Chuck Norris again. You know this kid now as Cecil.
You are not only a liar, but a poor liar. Not even God was able to survive a roundhouse kick from Chuck Norris.
Tangential to this- my favourite Chuckism: Chuck Norris does not sleep. He waits.
We’re all a day late and a dollar short on this one.

Yep…
We’re still in on the ground floor of Wilford Brimlyisms though!
