What's that light?

I had some good luck in the form of a flat tire this morning. I know you're wondering "how is that lucky, you idiot?"...

So I'm cruising on the highway this morning towards work when a warning light appears on my dash. I had never seen this light before and I couldn't readily identify it. I know it was bad. How do I know this? by the '!' in the middle of it. It looked kinda like a droplet of liquid around it with a comb at the bottom so I was all "what the fuck?"

I take the very next exit (which is what you do when an unidentified warning light appears when you are on the highway) so happens that's where my dealership is. So I pull the fuck in there and say, "yo what does that mean?"

Dude says, "Tire pressure bad." He then looks at all my tires and asks me to roll back slowly so he can watch this one tire. He goes yup you got a flat. I'm all what do you mean flat? Look. OK. Sonofabitch there is a screw sticking up out of my tread. He points out that it is in fact hissing. Sure as shit. Well fuck how much is this gonna cost? Nothing. Sweet. And they drove me the fuck to work. Gotta like that. So I went out to lunch with my old boss who left the company about a year ago and he drops me off at the dealership to get the car. See that was a flat lucky tire...
