It all goes back to Baycon '98. Which is a huge San Francisco Bay area Sci Fi convention. I love it dearly despite its recent spats with my local anime con Fanime. Baycon is a huge party con. I spent a lot of time at a party called Mara's Bar, which was Klingon themed. Klingon music, slave auction, people dressed up in great costumes, so on. While there, I happened to catch sight of a man in full Klingon makeup, with the robes and saber of a Jedi. Since I'm also a huge Star Trek fan, moreso at the time as well, it just clicked as the perfect pairing of two of my favorite things.
