CALL THE FIRE BRIGADE!

Good for you, you accidentally set fire to a cardboard box. Oh, wait. What am I saying. That's bad! That's really bad! Your efforts to put out the fire have only been making it worse, you really should call a professional in.

Now I'm going to get out of here before the fire spreads, and you'd better get to a phone and dial 911/999/whatever the emergency service's number is around here. I don't care who you get. Who do you want to save the day?
