One very important lesson that I have learned over the years, is that boys like to play with fire. It doesn't matter whether it's an actual fire, fire or relationship fire, or flirtation fire, etc. Someone managed to bring an extra dresser (or they stole it from some homeless guy in the mountains that only had a dresser and a fish-hook to his name) and decided to put it onto the fire. A common equation for boys: Fire+Something to make it Bigger=Happiness.
Now, not only do they have to make the fire bigger, they have to profess their manliness by hitting it with something, physically jumping over it, or seeing who can handle the heat the longest. Do I understand it? No. Do I laugh at it? Yes.
HUZAH FOR FIRE!
