Bernadette: Hey, I'm gonna take tomorrow off so we can spend the whole day running the act.
Howard: You know what, it has been so much fun working on this with you, but-
Bernadette: But what?
Howard: It hasn't.

Bernadette: Look, I get that you're scared, but we just have to push past that.
Howard: I'm not scared. I don't like the act. It's over-the-top and weird and has more jazz hands than magic.
Bernadette: Why didn't you say something earlier?
Howard: You seemed like you were so happy, and then when I tried to say something, you seemed like you were so mad.

Sheldon: It's interesting. I've always thought that my father's journey and my own were so different, but he also faced failure and setbacks. Maybe our lives mirrored each other more than I thought. Maybe our lives mirrored each other more than I thought.

Amy: So, from one viewpoint, you and your father's lives are asymmetrical, but from another vantage point, they're symmetrical. Sheldon, what if symmetry and asymmetry are observer-relative? That would mean that the Russian paper was right-
Sheldon: But only from one perspective. If we look at it from a deeper view in more dimensions, our theory still stands.
Amy: Not only stands, it might be an even bigger idea than the one we were originally proposing.
Sheldon: Go get your laptop. We have a paper to fix.
