A San Francisco man was enjoying some adult videos in a private booth inside an area porn shop Wednesday when something stunning happened: he burst into flames.

Luckily, there was a firetruck only a block away, so when the human fireball rushed out into the street the firefighters were able to help him.

The man suffered third-degree burns and is currently in critical condition at a San Francisco hospital.

Arson investigators are not sure what set off the flame, and there is no word on which "steaming hot" video the man was watching when he combusted.
