Russian Mothers Milk (in a large Shot Glass). 1.5-3 oz Stoli or Absolut Vodka (go big like russky) 1 oz DeKuyper Butterscotch Schnapps 1/2 oz Baileys Irish Cream Pour in Vodka. Pour the Butterscotch Schnapps slowly on the slide of the Shot Glass, as if to layer. Then, carefully layer or float the Irish Cream on top, and serve. Throw the entire shot into your mouth without swallowing, swish around from cheek to cheek several times and then down the hatch.
