Why a fifth is now a fourth.........
Along time ago in a galaxy far far away..........
You could biy liquor by the quart.
You could also buy 4/5th's of a quart commonly known as a fifth.
Nowadays you buy liquor by the liter.
You can also buy 3/4 of a liter or 750ml.
This to me should be a fourth, yet go to any liquor store and ask for a fourth and they'll look at you like your from another planet.
