For a period in every kid's life, any roll of wrapping paper or long stick automatically becomes a lightsaber, though this usually passes once you grow up, or the videos surface on YouTube and your life is ruined. For some grown-ups who never got the message, go
laugh at intently watch, and potentially join the Pennsylvania Jedi
The PA Jedi are a group of "amateur actors" based in Philly, dedicated to expanding and refining their understanding of Star Wars-style lightsaber combat, then choreographing their own battles to raise money for charity/permanent virginity. Entering their totally normal and cool world involves visiting a Friday night practice, where you'll be named an Initiate, then borrow a wood/metal practice saber to learn the basics of combat, culled from American fencing and Shii-Cho (the fighting style from the SW films); stick with it and you'll create a character and start scaling their ranks, from Padawan, to Knight, to Master, coincidentally the same title you had on your birthday mail the last time you did any of this stuff. Because it's apparently more than just flailing about and making "whoosh" sounds, combat moves are broken up into 26 sequences keyed to letters (G=left hip strike, right hip strike; U=chest thrust, parry); skilled fighters can also arrange "freestyle battles", though if any of them went to Cranbrook, they're like, totally screwed
As cardboard tubes break and wood looks lame, there're dudes in the group that can craft you a metal/LED battle-ready saber that lights up, just like your face when you see a roll of wrapping paper. Because, um...wrapping stuff is awesome. Yeah, that's the ticket.
