After the recent passing of George Carlin, one of the first things that popped into my mind was "It won't be long before the alleged Carlin quotes start circulating again". Not that they ever stopped while he was still in the land of the living.
Sure enough, this morning I got notification of a new posting over at Snopes.com -- George Carlin on Aging -- debunking the rumoured Carlin quote.
If you reading this, take note. If someone sends you the email, send it back to them with a link to Snopes.com and correct them!
You can also find Carlin's own view of these quotes on his own web site.
