In case there was any doubt, here is another proof of the courage of firefighters: watch as this man stands with his hose right next to a blazing car and the car explodes literally on his face.

And yet, he keeps drenching it like nothing really happened. Two words: Steel balls. And steel everything too. This guy is tougher than the Wolverine.

The burning car was at the beginning of Detroit Street, in Los Angeles. Oh, the irony. [YouTube via Buzzfeed]
