Open the beer and pour it into the highball glass so that it's about half full.
Take the Amaretto and jigger. Using the jigger, measure .75 oz of Amaretto and pour it into the shot glass.
Take the 151 rum and jigger. Using the jigger, measure .25 oz of 151 rum.
Take the bar spoon and put it into the shot glass upside down just above the amaretto. Slowly pour the 151 over the back of the bar spoon so it lays on top of the amaretto.
(CAREFULLY) take the lighter and light the 151 on fire. After it burns for a few seconds, blow it out.
Then, take the shot glass (careful, it might be hot) and drop it into the highball glass with the beer.
