I was going to mention the whole stop, drop and roll thing... because it is laughably stupid, yet funny how he just runs around.
But he would have to flail around like he was having a siezure, and even then if he managed to get himself out, it would probably have been because theres snow on the ground.... you can't put yourself out using that method if you're dealing with flammable liquids. You have to snuff them with a blanket or chemicals.
