Pour in the Kahlua. Carefully add Bailey's to create layers. Carefully pour rum onto that. Rum should pool on the top. Next, Light the rum on fire, and take the shot with a straw.
A real B-52 is lit on fire. If you're too scared to drink it with a straw, put out the fire my smothering it quickly with your hand (don't try to blow it out!!!!). If you do want to attempt the straw, make sure to move fast, otherwise it can result in injury.
