You've probably heard about the passing of comedian, George Carlin. You may think it's an exaggeration to call him a defender of the Constitution, but that's how I think of him. By challenging the laws against "obscene" language, he got people talking about freedom of speech and the Constitution. He continued to perform his routine, "Seven Words You Can Never Say on Television," despite being subjected to arrest. The man had guts and a deep conviction in Americans' rights to protest.
It is best to watch him perform--
Second best would be to listen to him, which you can do by borrowing his When Will Jesus Bring the Pork Chops? [AB/CD 818 CAR]. You can, of course, read his When Will Jesus Bring the Pork Chops?, Brain Droppings, or Napalm & Silly Putty [all 818 CAR], but it's not quite the same as hearing or seeing him perform!
