Quote from Gloria in The Escape
Fred: The stroke may have scrambled some of Becky's memories. Mitchell: So she doesn't remember me coming out? Fred: Correct. And now presumes you're straight. That part I can't explain. Phil: [quietly] Have you tried popping her on the noggin? Jay: She's not a jukebox, Fonzie. Gloria: And besides, it doesn't work. It only made my uncle worse. He never woke up.
