Chuck Norris has already been to Mars; that's why there are no signs of life there.

They once made a Chuck Norris toilet paper, but it wouldn't take shit from anybody.

A blind man once stepped on Chuck Norris' shoe. Chuck replied, "Don't you know who I am? I'm Chuck Norris!" The mere mention of his name cured this man blindness. Sadly the first, last, and only thing this man ever saw, was a fatal roundhouse delivered by Chuck Norris.
