Let's say you've been asked to kill a troll. A very loud, very annoying troll that has mental breakdowns in the presence of chocolate. Do you deal with the troll by:
A. Getting a bunch of non-friends together and surrounding the troll before giving it The Death Of One Thousand And Five Paper Cuts.
B. Hiding it somewhere secure and handing it a supply of lipstick. Forget about killing the troll: there's a beauty contest coming up in nine days and how good are you going to look when you're next to a lipstick-covered troll?
C. Giving the troll a false magic item while convincing it that the geegaw will protect it from all harm and destroy its enemies, then watch it walk into the ambush that holds the numbers necessary to kill the troll anyway?
D. (Insert your own option here)
Note that trolls regenerate and will be back in nine days to wreak its extremely impotent revenge.
