It's been a while.

From BigFella:

I think the trick is not having a certain "magic bullet" that's the only way to kill the monster, but rather being open to unorthodox wacko crap that desperate players come up with when their pointy sticks aren't working.


It's the players' job to be clever, the GM's job is to give them something to be clever about and to inflict the ramifications of that cleverness in an even handed manner.
