OT:
"No, I am your pants!"
"You don't know the Pants of the Dark Side!"
"If you only knew the Pants of the Dark Side!"
"The pants is not as forgiving as I am."
"So I see you've constructed a new Pants."
"The Pants is your master now."
"There is no Pants, don't make me destroy you."
"Always with Pants, it cannot be done."
TAGGE
"Until this battle station is fully operational we are vulnerable to pants. The Rebel Alliance is too well equipped with pants. They're pants are more dangerous than you realise."
MOTTI
"They're pants are dangerous to your starfleet, Commander; not to this battle station!"
TAGGE
"The Rebel Alliance will continue to gain more pants from the Imperial Senate as long as..."
TARKIN
"The Imperial Senate will no longer be supplying pants, and will be of any concern to us. I have just recieved word that the Emperor has dissolved they're pants permanently. The last remnents of they're pants have been swept away."
TAGGE
"That's impossible. How will the Emperor maintain control of the pants without the bureaucracy?"
TARKIN
"The regional governors now have direct control over they're pants. Fear of our pants will keep the local systems in line. Fear of this battle station."
TAGGE
"And what of the Rebellion's pants? If the Rebels have obtained a complete technical readout of our pants, it is possible, however unlikely, that they might find a weakness in our pants, and exploit it."
VADER
"The pants you refer too will soon be back in our hands."
MOTTI
"Any attack on our pants made by the Rebels against this station would be a useless gesture, no matter what technical pants data they've obtained. Our pants are the ultimate power in the universe. I suggest we use them!"
VADER
"Dont be too proud of this technological pants terror you've constructed. The ability to destroy one's pants is insignificant next to the power of my pants."
MOTTI
"Dont try to frighten us with your sorcerer's pants, Lord Vader. Your sad devotion to your ancient pants has not helped you conjure up the stolen pants, or given you clairvoyance enough to find the Rebels hidden pant..."
VADER
"I find your lack of pants disturbing."
TARKIN
"Enough of this! Vader, release his pants!"
VADER
"As your pants wish."
TARKIN
"This bickering of pants is pointless. Lord Vader will provide us with the location of the Rebels pants by the time our pants are operational. We will then crush they're pants with one swift stroke!"
Ben Kenobi - "Vader was seduced by the Dark Pants of the Force"
"The force is what gives a Jedi his Pants. It surrounds us, penetrates us, and binds us to the galaxy"
"Your father wanted you have this when you were old enough, but your uncle wouldn't allow it, He thought you'd follow old ben on some damn fool idealistic crusade. It's your fathers Pants, the weapon of a jedi knight, from a more civilized age."
Had to rewrite a bit to make it funny, but it works.
