Qwepir that sounds badass.
My craziest kill had to be on balloon race. Loooong time ago, about a week or so after the Scout Update, I was still playing around with pre-nerf Sandman. I was on blu, and I was on the third point, capturing. The red ship was just pulling in, so I decided to launch a ball at them for no reason, knowing I wouldn't hit a thing.
Turns out, I hit a Pyro trying to jump onto the platform area early. This was from max stun range, plus he was over nothing, so he ended up falling into the abyss below. It was on Jcink's I think.
