1/2 shot amaretto almond liqueur
1/2 shot Bacardi® 151 rum
1/2 glass beer

Mix the Amaretto & Bacardi in one shot glass. Fill the beer mug 1/2 way with beer. Light the Bacardi & Amaretto with a match or lighter. Drop the flaming shot glass into the beer. It immediately begins to foam up. At this point gulp it down (be careful not to swallow the shot glass!).
