Here are a couple:
Clone Advisor: You'll have to make your way through the nursery facilities of the citadel.
Scorch: Oh -- is that where they keep the baby Wookiees?
Clone Advisor: Negative. Baby wroshyr trees. This is the Wookiees' garden.
Scorch: Well, the garden's got a pest problem: Trandoshans.
Sev: You would prefer baby Wookiees?
Scorch: Not really. Too cute.
Sev: Does anyone else find this planet a little... strange? ... That's what I'm talking about. It's a power generator, in the middle of a TREE. Strange.
Scorch: Sev, when this is over, I'm gonna make sure you get some R&R
Fixer: Looks like a textbook perimeter defense of a Trando camp.
Scorch: Either that or the Wookiees have taken up landscaping.
Scorch: Why don't we just fly out of here?
RAS Ship Computer: Engines offline.
Sev: I think ...I see it. A Trade Federation Battleship.
Scorch: Not even you can see into hyperspace, Sev.
Clone Trooper: Ah, one of the deluxe models. Come to save us with your 'superior' training?
Boss: This 'deluxe model' is the only thing standing between you and a bloody death, so you'd best be showing some respect, trooper.
Scorch:No terminal can match my l33t hax0r skillz!
Scorch:[after killing a Geonosian] Hey, Sev, this one looks like your mother.
Scorch:That was for Delta 23! ...or was that 32?
Dang, they're all funny. Those were just a couple from the site mentioned above.
