I actually never seen his comedy routines because I was naught but a child to watch it on tape, and I didn't exist in the 70s to 80s. I vaguely remember him from Thomas the Tank Engine, and various news reports about him as time went by. I've seen a few clips, they were of course funny as hell.
I'm saddened by these news, after the death of Tim Russert, I learned about a Japanese actress who also died of heart failure, and now George Carlin? I find myself wondering if this month could get any worse...
