Sorry about the corny episode title.
Transcript
Ric Olié: Coruscant. The entire planet is one big city.
Obi-Wan: What? Where do they grow food?
Ric Olié: They, uh... import it.
R2-D2: {aside conversation} So, we stopped off for three sessions on a gangster-ridden hive of scum and villainy to get weapons, and we didn't encounter a single ship on the way here?
Qui-Gon: {aside conversation} They were obviously scared of us.
Obi-Wan: For a planet-wide city? That would take... millions of space freighters per day.
Ric Olié: Maybe they grow it indoors in hydroponic gardens.
Obi-Wan: Which would require vast energy supplies and reserves of water. How do they generate enough energy to run this city anyway?
Ric Olié: Look, I'm just a pilot. I'm not the source of all the information here.
