George: What are you doing?
Missy: Watching Sheldon struggle with homework. It's so great.

Mary: Missy, if you want a minute with Dad before they close the casket, now's the time. [Missy looks unsure] It's okay if you don't.
Mary: I have to. [Missy stands up and walks up to her father's casket]
[flashback:]
George: Here, let me help you with that. Okay.
Missy: [eats] Holy moly.
George: It's good, huh?
Missy: Unbelievable.
George: I'll leave you to it.
Missy: No, sit with me.
George: Okay.
[present:]
Missy: [crying] Thank you for that. Thank you for everything. [sniffles] I love you.

Sheldon: Is Mom okay?
George: How the heck should I know?
Missy: She left. You can say "hell."

Dr. Sandra Thorpe: Have you always been that way?
Missy: I guess so. I think when you're on your own a lot, you get good at seeing that kind of stuff.
Dr. Sandra Thorpe: Really?
Missy: My dad does football with my older brother, so they're like a team. And my mom and meemaw spend all their time fussing over Sheldon, so they're like a team, too.
Dr. Sandra Thorpe: So no one's on your team?
Missy: Nope. It's just me.

Adult Sheldon: Engineering has a rich and storied history, dating back to ancient times. Some consider it the single most important field of study... Okay, w-wha... no. Stop. I'm sorry. Howard, I can't do this.
Howard Wolowitz: You asked me to write you an introduction to engineering.
Adult Sheldon: Yes, and if I wanted a comedy routine, I'd have gone to Billy Crystal.
Howard Wolowitz: Just let me read it. [clears throat] Engineering has a rich and storied history dating back to ancient times. Some consider it the single most important field of study known to man, from the wheel to the International Space Station, which I went to.
Adult Sheldon: Honestly, this again?
Howard Wolowitz: Like we don't hear about your Nobel Prize all the time.
Adult Sheldon: It's not my fault people ask about it.
Howard Wolowitz: Because you're always wearing it! You have it on right now.
Adult Sheldon: Look how shiny it is.
Howard Wolowitz: [sighs] Just tell your story.

Howard Wolowitz: Wait, so after all this time, that's your problem with engineering?
Adult Sheldon: Evidently.
Howard Wolowitz: So all the teasing and all the abuse had nothing to do with me?
Adult Sheldon: I'll admit, at first, I had a chip on my shoulder because of that class, but then it was mostly you.
Howard Wolowitz: Unbelievable. When will I learn?
Adult Sheldon: I could give you that answer, but if you figure it out for yourself, it'll mean so much more.
Howard Wolowitz: Goodbye, Sheldon.
Adult Sheldon: Bye.

Professor Boucher: For your design assignment, you may decide between suspension bridges, truss bridges, beam bridges, just not Beau Bridges. [silence] And people say engineers don't have a sense of humor. [Sheldon raises his hand] Yes?
Sheldon: What are Beau Bridges?
Professor Boucher: That's all for today.
