Oh, Never Mind

Me: Dad, how are you feeling tonight?  Your ears were bothering you so much when we drove down from Park City.  Are they still ringing now?
Dad: What?
Me:  Your ears.  How are your ears?
Dad:  My knee?  Well, the shot didn't help as much as last time.
Me: What about your ears?
Dad: My what?
Me: EARS!
Dad: Honey, I just can't hear you.  My ears have really been ringing since we drove back down the canyon.
