The double-ended laser sword. Now that is a seriously good way to cause major injuries to yourself. So you know anyone who dares to attempt to wield one of these suckers in battle is either incredibly good, or incredibly stupid. And if they were that stupid, they wouldn't be standing in front of you with all four limbs still attached.
Qui-Gon: Come on, Bubble! Show your traitorous goateed face!
GM: The door opens to reveal a figure in a black robe. You recognise him as the guy you attacked while escaping from Tatooine.
Qui-Gon: The bounty hunter! We draw our swords!
Obi-Wan: Wait... how did he get here?
Qui-Gon: He followed us, obviously. That's what bounty hunters do.
Obi-Wan: But how—
Black-Robed Figure: Out of my way, Jedi.
Obi-Wan: No, wai—
Qui-Gon: I roll a 19!
GM: He fires up his red laser sword.
Qui-Gon: All right, we've got him this time. Two of us to one of him!
GM: Did I mention it's a double-ended laser sword?
Qui-Gon: I knew we should have bought the 10-foot laser poles!
