So, my sister's friends built a trebuchet, for the heck of it, and then fired pumpkins from it.
They also wear kilts at every party occasion.
I think they're ready to be recruited into the SCA.
Here's the youtube video of the grand First Firing. You can see my sister and her boyfriend if you squint.
