1/2 glass of beer
3/4 shot of amaretto almond liqueur (or almond liqueur)
151 proof rum (or overproof rum)
Fill the shot glass about 3/4 full with amaretto and top it off with enough 151 proof rum to make it burn. Put the shot glass in another glass and fill the new glass with beer (right up to the level of the shot glass). \r
Light the amaretto/151 and let it burn a while. Blow it out (or leave it burning if you're brave) and slam it. Tastes just like Dr. Pepper.
