"Chucking a Norris" is another term for taking a shit. The legend goes, Chuck Norris once tried to coin the term "Chucking a Norris" to mean pooping, but everyone he said it to called him an idiot. Since he was Chuck Norris, they decided to humor him.
Instead of "How much wood would a woodchuck chuck if a woodchuck could chuck norris?"
How about How much wood would a chuck norris chuck if a chuck norris would chuck wood?
Obviously the answer is simple he would chuck all of it! And in response to the guy who asked how much wood could chuck Norris Chuck if Chuck Norris could chuck wood that's ridiculous!! Because all of the blood currently on Earth has already been checked by Chuck Norris before chuck chucked wood. Dumbass.
