The story goes something like this.

The Persian Gulf, circa 1950, American oil rig workers would
slip some vodka into their orange juice while working.
They used the most convenient tool for stirring the drink,
a screwdriver. 

This is such a simple and delicious drink. The quality of the
orange juice is actually more important than the vodka.
You can make an awesome screwdriver with cheap vodka,
and the screwdriver even has a few variations that build on the recipe.
