In Assassin's Creed multiplayer, everyone is trying to stab each other in spectacularly animated ways. If you spot your killer before he kills you, you can stun him, and he gets assigned a new target.
One time, as I approached my target, someone else stunned him. I stood over him for a minute as he lay on the ground, and pressed X to kill. I was expecting to lean down and stab him like normal, but instead my character simply kicked him in the face.
It was Lizard Dude.
