We missed the fact that the 17th anniversary of Team Fortress passed last week. We'd feel worse if Valve didn't miss it too. Here's their razzle dazzle on the topic: "Anyway, to celebrate our right-on-time, certainly-wasn't-on-August-24th birthday, we're pushing out an update! Just like last year, we're handing out Birthday Party Hats, which you can equip all year round, and Birthday Noise Makers, which can only be used over the next couple of days."
