I found my first hat the day before the first hats came out on Tf2. It was a batter's helmet.
One month later, I found my second hat which came out to be a pyro's beanie. One year later, I found my third hat, which turned out to be the soldier's stash. Now the rest of my hats, I just crafted which are currently the heavies' duty rag and the towering pillar of hats. It was a great TF2 life.
