Some guys in England were drinking in the living room when one of them decided to light his friend's bushy hair on fire. The friend is so out of it he doesn't even notice, so another guy has to lean over and put out the flames.
The guy shooting the video did the lighting, and he gets such a kick out of his friend's cluelessness that he sets his hair on fire AGAIN. This time the flames spread even more, so HE has to put it out. It even sets off the smoke alarm.
