Quote from Dorothy in Mister Terrific
Dorothy: Rose, don't argue with him. Mister Terrific, I think that Lex Luthor and The Joker are harassing an old lady in the stairwell. Could you come in and melt them with your X-ray vision? Rose: Mister Terrific doesn't have X-ray vision. Dorothy: Please, Rose! This is no time to point out his shortcomings!
