1/2 a fluid ounce or 1.5 centilitres of Peach Schnapps
Drop of Irish Cream
Dash of Creme de Menthe

Pour schnapps into a shot glass and layer Irish Cream. Slowly layer the creme de menthe over the back of a spoon into the glass so it drips through the Irish Cream and the schnapps. Let it sit on your tongue for a second to get the full phlegm effect.
