Centuries ago, some not-yet-American folk ate a meal with a bunch of people they met and would later treat rather poorly. I'm sure there's an analogue in the Star Wars universe, somewhere. Jabba probably shared a turkey with Luke before attempting to feed him to the Rancor.
To celebrate Thanksgiving, Star Wars: The Old Republic is putting on a double XP weekend, getting characters up to snuff for the approaching Galactic Starfighter expansion. The event ends on Sunday, December 1st 11PM PST or December 2nd at 7AM GMT. It started an hour ago, so get cracking.
