You know, I hadn't considered a parcel-delivery use for the trebuchet but as you mention it I can see that it a totally logical and legitimate use and therefore having a trebuchet is clearly totally logical and legitimate.
It would eliminate them having to come over asking for a cup of sugar or to borrow a tool...Just hoik that bitch over on the trebuchet and you're done. Then, if they don't return the tool, send some fucking burning rolls of hay, some severed heads or a few boulders.
Exactly! Another use for it would be, if Grouchy's really getting on your nerves, you could just trebuchet that little bugger to the next county. The long walk home should prove a valuable lesson.
