I just realized that Keith says "All y'all" when he's drunk.
Watch it! Ain't nothing wrong with a good all y'all even dead sober.. I mean it pretty much works this way:
you = 1 person
y'all = 2-4 people (really 3 though)
all y'all = 4+
It's all basic math and ball bearings.
And man, I love my "Pale Chocolate Oat Malt Doesn't Have a Name Until I Gotta Write It Up Mild" - 4 Imperial Pints (or Imperial Dimpled Mugs) and still sober enough to sing in the church choir.
