100,000 years ago in a cave far, far away ...
CAVEMAN DUG: Hey Stu, we should squeeze the juice out of these grapes and put them in the water skin bags so we can have fresh juice in the morning with our rock fried bacon and dodo eggs.
CAVEMAN STU: I dunno. I don't care much for grape juice.
CAVEMAN DUG: Too late. I've already filled a bag for each of us. If you don't want yours I'll leave it here in the back of the cave and we can pick it up next year when we come back this way hunting. I'll just push this piece of cork in the top so it doesn't spill.
CAVEMAN STU: Whatever man.
One year later back at the cave.
CAVEMAN DUG: Hey Stu you gotta try this stale grape juice.
And the rest is history!
