How to make the One Night Stand #2 – Fill a Shot Glass with 1/2 oz. of Kahlúa® and 1/2 oz. of Vodka. Next, combine Baileys Irish Cream and Milk in a rocks glass. Take the shot of Kahlúa® and Vodka, and follow immediately with the chaser of Milk and Baileys! If the Baileys goes in on the edge it will sit suspended in the middle of the reddish liquid with a rounded shape like a liver or kidney. If you use an upside down spoon it will curdle very slightly and look like a brain or a lung.
