It's got to be...
++Grandalf
Not only one of the most famous pipe smokers ever, but sarcastic too. Bonus! And he's actually much more of a crusty old hippy than Elrond, he doesn't even have a house, he just crashes on other people's sofas for generations of Men and wanders round with unkempt beard and hair and a mucky old cloak. No wonder they turned him into Gandalf the White, he probably needed a bath.
