Bernadette: Hang on. You seriously think I'm going to live with your mother?
Sheldon: Howard, I think I can help here. Yes, Bernadette, that's exactly what he thinks.
Howard: Why not? It's a great house, plenty of room, and if we have kids, Mom's there to help. You know, when she tells the Three Little Pigs story, she actually has hair on her chinny-chin-chin.
Bernadette: I'm not gonna live with your mother. Not now, not ever.
Howard: Wow, someone obviously has some mommy issues.
