George: Dwayne, my friend and I would like to exchange frames. Could you put his lenses in my frames and mine in his?
Dwayne: Yeah, we can do that.
George: And I'd like a discount.
Dwayne: Why should I give you a discount?
George: Listen, you're lucking I'm not asking for a refund. You gave me ladies' frames!
Blind Man: What's that about ladies' frames?
