George Jr.: See, number one is also pretty funny, 'cause it means taking a leak. [Mary sighs]

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.

Meemaw: Hey, I put my time in on that, too.
June: Not as much as me.
Meemaw: When I met him, he was a mess.
June: [laughs] You should've seen where I started.
Meemaw: Well, I think we can both agree, he is one lucky turd.
June: Amen, sister.
