I remember switching PBS on one day and seeing him on Thomas the Tank Engine. At the time I had no idea why my parents found it so funny that George Carlin would be a on children's show. It was only later I found out how much good work he did in matters of free speech and artistic freedom.
There will only be one George. I liked his style and sense of irony. It was from him that I first heard the question posited that if "pro" is the opposite of "con", then is Congress the opposite of progress. The world is still trying to figure that one out. Also, I learned from him to just give an approximation of my baby's age. If she's 13 months, just say she's one year. If she's 19 months, just say she's one and a half.
