Adult Sheldon: Mr. Lundy was undeterred. He sought out new investors and new talent to bring cowboy aerobics to life.
Mr. Lundy: You've got the look. [chuckles] You've got the physique. If-if we could secure a star of your caliber, it would really put us on the map.
David Hasselhoff: I do look good in a cowboy hat.
Mr. Lundy: You look good in everything. [chuckles] Come on, Mr. Hasselhoff.
David Hasselhoff: Call me The Hoff.
Mr. Lundy: [chuckles] Okay, The Hoff. So, what do you say?
David Hasselhoff: Well, I've conquered television, music. I don't see why I couldn't add exercise videos to my empire.
Mr. Lundy: So you'll do it?
David Hasselhoff: You got The Hoff!
Mr. Lundy: Hot damn! I got The Hoff! [both laugh] By-by any chance, do you know what size chaps you wear?
David Hasselhoff: Oh. I got my own.
Mr. Lundy: Of course you do.

Adult Sheldon: I know what you're thinking: she's going to tear his throat out. But what in fact happened is she did what she thought Jesus would do. She went home and made that tuna casserole. It was a little salty but I ate it because she was in a mood.

Mr. Lundy: Can I help you?
Sheldon: I'm interested in becoming an actor.
Mr. Lundy: Well, good for you. You've come to the right place. You know, I-I've been a professional actor for years and years.
Sheldon: Really? What have you been in?
Mr. Lundy: Well, have you seen the mattress madness commercials on channel 68? [cut to a cheesy commercial] "I'm soft and firm in all the right places".

Sheldon: Excuse me, is there someone in charge here?
Mr. Lundy: That would be me.
Sheldon: Mr. Lundy? What are you doing here?
Mr. Lundy: I'm the realtor.
Sheldon: But you're a teacher and an actor.
Mr. Lundy: And while those both pay so well, I like to do this on the weekends for fun. [chuckles] Why are you here?
Sheldon: I live next door and I'm concerned about who the new neighbor might be.
Mr. Lundy: Don't you worry, I will personally make sure that your new neighbor is whoever forks over the most money.
Sheldon: Thank you. Wait.

George Jr.: What is this?
Meemaw: That's the exercise guy Meemaw likes.
George Jr.: I can't believe anyone pays money to watch old people sweat.
Missy: 40 bucks?
George Jr.: They sold over a million of those? At 40 bucks a pop? Do you know how much money that must be?
Missy: I'm not a calculator.
[later:]
George Jr.: 40 times... one million. That's 40 million!
Missy: Whoa.

Adult Sheldon: Behind every great scientist, there were often unsung helpers toiling away in the background. Presenting... "Great Lab Assistants in Scientific History" When Alexander Graham Bell needed an assistant, it was Thomas Augustus Watson who answered the call. [laughs] Get it? "The call". [snickers] Madame Curie's daughter Irène was also her lab assistant. Irène was so dedicated, she died of radiation poisoning. Unlike her sister Ève, who selfishly lived to 102. Lastly, Émile Roux was assistant to Louis Pasteur. When they worked on the rabies vaccine, Roux kept a loaded gun in the lab to shoot Pasteur in the head if he got infected. He never had to, but it's fun to know he would have.
Dr. Linkletter: No, Sheldon. You can't be my lab assistant.
Sheldon: Maybe you weren't paying attention. I'll start over. Behind every great scientist, there was a dedicated as...

Adult Sheldon: While not the lab work I hoped to be doing, it did feel good to be part of an actual experiment. A tedious, menial part that could be performed by a monkey. Or worse, an engineer.
