Greedo
Han Solo sits at a table, alone. He sees a guy at the bar who he knows used to have a blaster. Chewie has just frisked the guy and he seems to be clean. Han blasts the guy, reducing him to a puddle of smoking protoplasm.
"He's not going to get me now!" Han says proudly, holstering his weapon.
The bartender moans, thinking of the mess he has to clean up.
Meanwhile, every other scumbag in the place has drawn it's weapon and is taking aim at Solo.
