A quick Google search for a Firefly Drinking Game reveals that neither of the main contenders (from FireflyWiki and DrinkiWiki respectively, largely stolen off each other from the looks of it) suggest doing anything when Mal punches out or otherwise threatens a member of his own crew. Seriously, folks. How could you miss that?

I also note the absence of any activity pertaining to a member of the crew being seriously injured in a firefight. I'm pretty sure they all got shot at one point or another during the TV series, with the possible exception of Inara.
