Wow. I just got in from a very, very late flight from Denver, and the early-morning newscasts hit me with this wallop: my favorite comedian, George Carlin, passed away last night. On Sunday, he admitted himself into a local Santa Monica hospital, complaining of chest pains, and ended up dying that evening of heart failure. He was 71.

Carlin, of course, is most famous for the 1970s comedy routine "Seven Words You Can Never Say on TV." It was a bit which not only got radio stations that played it in trouble with the FCC, leading to landmark First Amendment and decency rulings by the Supreme Court, but he was also arrested in Milwaukee on indecency charges after doing the routine on stage there.
