Synopsis: We find ourselves at the clinic watching John reassure Liz that installing the appliance wasn't going to hurt because he doesn't understand why she's objecting to it. He then says that the appliance will take a bit of getting used to but no one is going to notice it's there. He is left dumbstruck when she says something like "Are you abtholutely sthure about that, Daddy?" because he realized too late that it affects the way she speaks.
Summary: He's not going to let that bother him though. If people tease her, it's for the reason her teacher hands out.
