Damn, I remember one time I was playing TF2, and I was killed by a Sentry, and when the screenshot thing came up, It was the most perfect shot to take, but I hadn't set a screenshot button yet. I was so pissed, it was a once in a lifetime screen shot oppurtunity.
So, it was on 2Fort, and I was a Pyro I believe, in Red Base, and theres that one square hole where you can drop from one of the upper levels, and there were like, 2 turrets up there, I was killed by the turret, and it zooms in on it, you can see the engy standing right behind the turret with his wrench.
And who is it you see right over the engy's shoulder? A spy from my team disguised as another engy! It looked so perfect, just some engy minding his own business, with some spy lurking over his shoulder!
