Speaking of Spies, here's a little story.
Last night we were playing Dustbowl, and in the third round we (BLU) took the first point, so everyone fell back to the second point. You guys probably know that RED engies usually hide a teleporter in that little room that leads to their spawn so that they can still get to the first point after the spawn door locks. Usually a BLU demo will go up there and get rid of that crap, but I guess none of our demos decided to check.
So everyone (RED and BLU) was pretty much concentrating on that second point, and I got killed and respawned back at the BLU spawn. Everyone knows I almost always play Pyro, and whenever the coast is clear I like to fire off my flare gun for fun/target practice. We've got no teleporter, so I'm making my way to the second point and I decided--on a whim--to shoot a flare into that room that leads to the RED spawn.
All of the sudden, someone lights up. I hit a cloaked RED spy. I had no idea he was there. I quickly backburnered him as he ran away and then starting laughing my ass off.
