Hmmm...possible that he took it from Whitman. I like WW a lot.

No idea about the whiskey during DVD signings, I didn't/don't follow Gale, only when he's on tv...at least, I stopped following his every move around the time he did Vanished. As far as the pothead thing goes, it's kind of a not-secret secret. Can't point you towards anything specific. Others may be able to. I do know that Hal has said it several times, although a lot of people dismiss that as this hate/hate thing that Hal has for Gale.
