bet he had a funny look on his face. i screwed up in a kitchen once poured window cleaner on a hot griddle instead of grill cleaner. found out that the vapor ignited. luckily for me, and unluckily for him another guy saw me back away from the grill and came over to see what was going on right as it ignited. he made a shadow in the fireball for me. it went by both siddes of me was warm but didn't even singe my hair. he got cooked pretty good. thankfully only second degree
