Who's your daddy?

DARTH VADER: "Brom never told you about your father, Eragon...I am your father!"
ERAGON: "My father was Morzan, he betrayed and purged the Dragon Riders with Galbatorix, my mother left and gave birth to me before she died and I grew up with my uncle and aunt."
VADER: "Hmm... that sounds familier... oh well."

VADER: "The elves never told you what happened to your ancestors and your father. I am your father Aragorn!"
ARAGORN: "What are you babbling about? My father was Arathorn!"
VADER: "Are you sure?"
ARAGORN: "Positive."
VADER: "Um... okay, my bad."

VADER: "Bilbo never told you what happened to your father! I am your father, Frodo!"
FRODO: "Don't be ridiculous. My father was Drogo. He died when I was little, in a boating accident.
VADER: "Damn!"

VADER: "Dumbledore never told you-"
HARRY: "My father was James Potter!!!, he was killed by Voldermont"
VADER: "Voldermont? That pansy?"
HARRY: "Yeah... duuude... you have an obsession."

*Luke walks in*
LUKE to VADER: "Father?"
VADER: "Who the hell are you??"
