Dr. Cox: Okay, I'm Dr. Cox, and this is... my gal, Friday; she'll be helping me to take care of you but, before we get under way, we're gonna need you to ease up on the yakety-yak.

Dr. Cox: Yak, schmack, the lips stay zipped.
J.D.: Zipped, schmipped... Oh, I thought we were riffing.
Dr. Cox: Yeah, we're not.
