Really?! (sure beats trying to smuggle it in your boot!) ~ Going on a cruise and don't want to spend a fortune on drinks? Pour your vodka in an empty Listerine bottle, add 3 drops of blue food coloring and 1 drop of green. Wa-la! You now have a 5th of vodka to use for your beverages!!! If you drink a dark liquor, like whiskey, simply use the white listerine bottles!
