Pour Kahlua into shot glass to about 1/2 full.
Using a spoon(inverted), slowly pour in the Peppermint Schnapps until glass is about 3/4 full.
Done correctly, the Schnapps will flow under the Kahlua for a clear layer.
Again using a spoon, but this time right side up, slowly top off the glass with a layer of Bailey's.
Be careful to place the spoon right at the top of the Kahlua layer and to raise it as the glass fills up.
Done correctly, this will provide a layer of Bailey's floating over the Kahlua.
Toss it down all at once for something like a Peppermint Pattie, WITH A BANG!!! NOTE: Best if all ingredients are chilled
Serve: Shot glass
