I couldn't believe it when I heard this on the radio this morning. I've had the great fortune of meeting a few celebrities, and George Carlin always stands out in my mind as one who was a thoroughly nice guy, as mentioned by Bountyone. I've met several who looked down their nose at you or acted as if you weren't there at all, or worse, make your job harder--Carlin acted like we were people and chatted with us while the crowd gathered. What a shame.
