And for my second bloody show question -

After a hand to hand fight, the victim is stabbed.  Again, we have to see the blood.  Because of all the activity right before the stabbing, I'm a little concerned about going with pre-slit plastic bags.

We don't have any nice retractable blade knives, anyhow, and I'd like to use one with a retractable blade AND a blood bladder.  At least, I'm assuming that's the best way to stab-n-bleed.  Any suggestions for sources?  Or simple rigging?

Thanks.

If all of your replies are going to make me laugh as hard as "Sam Peckinpah" did, I don't think I should mention the show - just to keep the entertaining guesses going.

We are doing Jane Martin's "Flaming Guns of the Purple Sage - a 'B' Western Horror Flick for the Stage."  We also have to have a garbage bag full of human body parts.  Oh, and the shooting victim then drinks a beer that we see come out of his bullet holes.  Fun times ...
