1/2 shot Amaretto
1/4 shot Kahlua
1/8 shot Root beer schnapps
151 proof rum
1/2 glass Beer

Beer mug

In the shot glass, pour amaretto, then kahlua, then root beer schnapps. Finally float rum on top. Fill a beer mug (with something like bud or coors) half way. Light shot on fire, drop into beer mug and slam as fast as you can! By the way, the faster its slamed, the more it tastes like Dr. Pepper
