Flaming Dr. Pepper
Fill a glass mug with any lager of choice (I usually go with the cheapest because this drink tastes amazing regardless)
Fill 1/2 a shot glass with amaretto (I go with Disaronno), then fill the last half with bicardi 151. Light the shot on fire.
Pick up the shot (while on fire) and drop it into the filled beer mug, and chug.
Tastes exactly like Dr. Pepper if you do it right
