ESB Family Reunion...
Vader (flipping a steak): Obi-wan never told you about your father...
Luke (about to eat one of Vader's steak): He told me enough; he told me he barbeques better than you.
Vader: No, I am your father.
Luke (astonished): No... That's not true... THAT's IMPOSSIBLE!
Vader: Taste your steak; you know it to be true.
Luke tastes the steak and is convinced Vader does know the Skywalker Secret Recipe...
