Jedi vs Sith? Hmm, that's a very interesting question actually. Reminds me of a story of my own regarding such a clusterfuck argument.
I remember there was this one time, around six years ago or so, me and my buddy Jerome were arguing about the exact same thing. We had just finished watching Star Wars 4 through 6, and my friend, entirely out of the blue, blurted out "The Sith would totally own all the Jedi's asses."
I was stunned for a few seconds, unable to respond to this blasphemy that my friend (whom I assumed was a staunch ally of the Jedi) suddenly uttered. Aghast, I rebutted with the only thing I could think of at that time: "I want you... Deep inside me."
Upon realizing what I had just said, I immediately looked away from Jerome. Boy, was I embarrassed! I was so red-faced then, and I think the room remained silent for about two minutes or so, with the both of us just staring at the floor. Jerome was the first one to speak up again, because I just couldn't dare to say another word after that major blunder. He looked at me wryly, scratched his head and said "So, uh... You wanna go do it?" At first I didn't really know what he was talking about, because I was still thinking about what an idiot I was for saying what I just said. After a few moments, though, I finally grasped what he was trying to tell me. "Sure," I said, with a faint smile forming at the corner of my mouth.
My pants were beginning to feel tight by then, and I could notice the same thing happening to Jerome.
He ambled closer to me, the bulge of his erection now quite visible. He moved his face close to mine, our lips almost touching, and whispered "Kiss me, Fred." His voice was hot and silky, making me long for him even more. My penis was was now fully erect, too, and I could feel his hand running slowly through its length...
..Well, what happened next would really be too graphic for a board like this, so I'll just leave out the raunchier details. I will say this, though: Jerome was one hell of a F*ck. He could do stuff wit his tongue that I could only dream of! And don't even get me started about that cock! Just thinking about it gives me goosebumps.
So anyway, I guess the answer to the age old mystery of who would win in a fight between the Jedi and the Sith would be this: "Gay sex is the sh*t!"
