In these tougher times, many of us are drinking Box wine, and there is always one more glass in the box after the normal process or using the spout/nozzle
Rip open the Box (use a a fire starter) and flatten out the plastic bag. Grab all four corners with the spout pointed down....Looks like a flying squirrel.
Drain out all the remaining wine to the spout/nozzle and pour into glass.
No more wine ? "No, I used the last, had to Flying Squirrel it"
