Hilarious stuff, and hat tip to Muffins from the nom-nom-nom.us forums where I stumbled across this image.  If you're looking for an idle server to wait out the unlock drop fix, I've had great luck with Ratty's servers.  Not to mention his homepage is fantastic!

In other news, there's a humorous entry in the tf_english.txt string file, located in team fortress 2 content.gcf -> /resource/

> "TF_MMO_LFG"        "Looking For Group"
> "TF_MMO_Quest1"        "You must kill %s1 %s2 to complete this quest."

Great joke, Valve.  Now fix the drop system, would you kindly?
