Greedo I've been looking forward to killing you for a long time.
Han: I bet you have.
Suddenly the slimy alien disappears in a blinding flash of light. Han pulls his smoking gun from beneath the table as the other patron look on in bemused amazement. Han gets up and starts out of the cantina, flipping the bartender some coins as he leaves.
"Over my dead body," Solo said unamiably.
[Greedo] was not impressed. "If you insist. Will you come outside with me, or must I finish it here?"
"I don't think they'd like another killing in here," Solo pointed out.
Something which might have been a laugh came from the creature's translator. "They'd hardly notice. Get up, Solo. I've been looking forward to this for a long time. You've embarrassed me in front of Jabba for the last time."
"I think you're right."
Light and noise filled the little corner of the cantina, and when it had faded, all that remained of the unctuous alien was a smoking, slimy spot on the stone floor.
Solo brought his hand to the smoking weapon it held out from beneath the table, drawing bemused stares from several of the cantina's patrons and clucking sounds from its more knowledgeable ones. They had known the creature had committed its fatal mistake in allowing Solo the chance to get his hands under cover.
