the most awesome kill animations\sync kills you saw

At times there are moments that a kill is highly dramatic and sometimes even awesome, like the moments in Dawn of War where you get to see spectacular sync kills from any faction or the knife kill animations of Battlefield 3.

So, what sync kill moment do you find spectacular or that impressed you?

As for me, one of the amusing things I saw was the Crysis 2 stealth kills that either snaps the neck or knifes the chest.
