Muriel tells Courage that she can't hear him without her glasses. She can't see without them, not hear without them.
Police Officer: See? There you are with the diamond.
Muriel: Courage, you know, I can't hear without my glasses.
Eustace: Stupid dog!
Di Lung: Dog not know when to quit.
Mecha Courage: Bow wow.
Di Lung: He better than you. He better than you in every way. He better than you in every other way. You never gonna beat him. Never ever gonna beat him. Never ever gonna beat him. Not even if you were gladiator, in Colisseum, in Rome!
Maria: Our casa is your casa! (To herself) Which means what's mine is yours, and what's yours is mine... all mine!
Di Lung: Noooooooo! You not know when to give up! Worn Mecha Courage out!
Eustace: (Referring to Mecha Courage) You're not such a stupid dog, after all! But you're still a stupid dog!
Muriel: I guess the only thing I can see without my glasses is Eustace's big shiny head!
