When Batman and Vicki are fleeing from The Joker's machine gun-totting goons, he asks her, "How much do you weigh?", and she replies, "About 108 , I think." Bats then uses his grappling hook to send Vicki to safety while he takes on the thugs on the ground below. After he's done dealing with them, he catches up to Vicki and tells her, "You weigh a little more than 108", and she sarcastically replies, "Oh, really?" It's a hilarious scene if also totally weird and pretty pointless: what a bizarre thing to say to her.
