Incase of fire what would I run out with?

So a few months back I was taking a shower one evening and began to hear some sort of a ringing bell, I thought it was nothing and just someone's loud smoke alarm going off because they probably left the stove on and their pot of spaghetti ran out of water and which eventually evaporated and burned the spaghetti, anyway, so as I finish my shower and still hear the ringing bell I start to wonder what that strange sound it, it sounded like a school bell going off indicating the end of class like we had in high school. So I get dressed and open up my front door and it's definitely not a school bell but rather the fire alarm, so I nonchalantly get my wallet keys, and cellphone and walk out of the building to find the rest of the tenants also waiting outside for a firetruck to come and turn off that annoying bell. Supposedly someone had pulled the fire alarm switch setting the bells ringing, I'm happy it just wasn't in the middle of the night. So it got me thinking if this was a real alarm what would I run out of the house with? Would I run out with my computer, but that would take time unplugging all the cables... should I run out with at least some form of id, I don't know... if all you people in the blog world had to run out with one thing what would it be? I think that at the least I should run out with some soap, toothpaste /brush and deodorant so that at least if I have to spend time in a shelter I won't stink :), or maybe I should take a fire extinguisher with me so that if there is a path that I need to walk through to get to safety but on fire, I can at least reduce the flames a little bit. I bet I would probably be too frantic and not even remember to take anything if the time came when I needed to run out.
