damn this is so cheap and cheesey....
AT the very end when they think its over and its time to leave have the biggest guy you can find jump out from behing bushes/coner of the building/ running out of the woods flailing a running chain saw chase you around the corner out of sight you scream as in pain and go silent..... let him cut up some soft wod to bog the saw for a few seconds them come back out after the group. Would work best if the saw was clean as he came out and covered in a red corn syrup when he came back
When in doubt, get the hell out - Jason Hawes
Of all the things I have taught you, remember this:
If you see me running, KEEP UP! - Joe Dog
