Free hats? Why would you ever turn down free hats?
Oh, I guess that's a good reason.
This excellent Source Filmmaker video by zombiller depicts a Team Fortress character's dream: free hats! Free hats everywhere! But something seems a little... off. Without spoiling it, I'll just note that wearing hats with a tendency to writhe and hiss menacingly is rarely a good idea.
OK, I will spoil this part, because this part is wonderful and should -- like a headcrab -- be shared with friends, family, and everyone you know.
Did I say should? Haha, I meant should not. Should not. Definitely not... the other thing.
...Hey, want a free hat?
