Unlike some Galactic Empires that just dumps out it's garbage before jumping into hyper space, the United Galaxy picks up after itself.
Do you have a urge to:
Explore strange new worlds
Meeting intresting alien creatures
Pick up trash.
Then the United Galactic Sanitation Patrol need manly beings like "YOU" to don the blue jumpsuit.
Take command our state of the art garbage scows and proclaim to the universe that it should....
"Give us your garbage." *
