I use whatever's more convenient. There's nothing like kicking a baby right in the nuts; it really calms me down when I don't like the results of a video game survey.
What about female babies? On the topic of boobs, I guess you could punch/kick their undeveloped boobs. I've heard it hurts quite a bit, so it should be satisfying enough when a server crashes. Kick in the groin ,however, outclasses a boob punch.
