1 cup beer
1 fluid ounce amaretto liqueur
1/4 fluid ounce 151 proof rum
Fill a pint glass half full of beer.
Pour the amaretto into a standard shot glass. Carefully pour the 151 proof rum on top of the amaretto so that it floats.
Carefully light the shot on fire by touching with open flame. Drop the lit shot into the half full glass of beer and slam.
