Vader: "Turn to the dark side and join me!"
Luke: "I'll never join you! You killed my father!"
Vader: "No Luke. I am your father!"
Luke: "That's not true! That's impossible!"
Vader: "And princess Leia is your sister!"
Luke: "That's not true! That's... improbable"

Luke: "That's...... very unlikely."

Luke: "Look, if you're not gonna take this seriously, I'm out."
