Flaming Dr Pepper... make sure you blow out the flame before drinking ;)

1/2 glass beer
3/4 shot Disaronno Amaretto Almond Liqueur
1/4 oz Bacardi 151 proof rum

Fill a shot glass about 3/4 full with amaretto and top it off with rum.
Ignite the amaretto/151 and let it burn for a while.
Drop it in a glass of beer and drink it fast (make sure before drinking that the flame is out).
Tastes just like a Dr. Pepper soda.
