I can only guess what the production meeting for that scene must have been like.
"OK, we've got a Klingon who looks like an 80's hair band refugee, looking through his spaceship's periscope whilst taking pot shots at an old space probe. What? Of course it doesn't advance the plot, but we have 50 bucks left over in the effects budget we need to burn. Now, how can we make this scene any more ridiculous? That's it! Make the probe scream when it gets shot! It worked for Lucas, and he's stinking rich..."
