Korriban joke

I got out of a confrontation with the other students by telling a joke.  IIRC it went something like this

There are these 2 mandolorians out on patrol.  One of them gets shot and can't move.  So his friend calls on the radio and asks what he should do.  The response is "First, make sure he's dead."  A blaster shot rings out over the radio.  "Ok, now what?"

That's how I remember it and it is definitely a sign I wasn't playing the game well.  Is there a better joke if you play a better character?
