Had one happen tonight at school. Someone said something to the effect of "Your'e pretty smart". My automatic response (AKA auto-taunt), was "faster, stronger, better." I was like "oh sorry, just something I heard on a video game..."
I physically dodged off a wall once or twice. Not really to the same velocity as an unreal pawn though. I've also tried actual dodge moves, even mimicking the jump sound as I do it, I can't dodge very fast, or more then 2 feet though.
Also, I look at real buildings and try to figure out, can an unreal player survive a fall from that height?
