Forgot to post this one... It's called Mind Erasers:
2 oz vodka
2 oz Kahlua coffee liqueur (any coffee liqueur works)
2 oz tonic water
Pour gently in layers over ice using a spoon as a diffuser. Pour the liquid over the back side of a spoon placed over the ice so the layers don't mix too much: 1st/bottom layer is Vodka, 2nd/middle layer is Kahlua, 3rd/top layer is Tonic. Drink as A SHOT through a straw from the bottom of the glass (Vodka followed by Kahlua followed by Tonic). Just suck it up through the straw all in one go.
