3/4 oz of vanilla vodka
3/4 oz of Malibu coconut rum (or Coconut Rum)
2-3 drops of half-and-half (or cream)
Mix the vodka and Malibu and pour into a double-shot glass. Using a straw that has half and half in it, (by holding your finger on one end) slowly drip a few drops into the shot. The effect is disgusting and amazing. Serve.
