Mary: [on the phone] Dr. Linkletter, what can I do for you?
Dr. Linkletter: Hello, Mrs. Cooper. I just wanted to let you know, with Dr. Sturgis away, I'll be available should Sheldon need anything.
Mary: Oh, that is very comforting to know. Thank you so much.
Dr. Linkletter: His well-being is important to me, as was made abundantly clear by my boss.
Mary: Okay, well, we are truly grateful.
Dr. Linkletter: Now, I'm not terribly experienced around children. If he needs to use the restroom, I don't have to go in with him, do I?

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Are we in my office?
Sheldon: No.
Dr. Linkletter: Then these are not my office hours.
Sheldon: Are you using my love of schedules against me?
Dr. Linkletter: [chuckles] Oh, yes.
Sheldon: Well done.

Dr. Linkletter: Sheldon, thank you for coming in. I want to apologize for our little tiff earlier.
Sheldon: You're forgiven.
Dr. Linkletter: Oh. Great. I found something that might be of interest to you. An authentic signature from Richard Feynman.
Sheldon: Where did you get this?
Dr. Linkletter: Details aren't important.
Sheldon: Is this a restraining order?
Dr. Linkletter: Not important.
Sheldon: That's actually a really good way to get autographs. I'll have to keep that in mind.

Jim: Here we are. Grab a shovel and dig in. There you go.
Dr. Linkletter: I spent the summer in Italy once.
Georgie: Bringing back memories?
Dr. Linkletter: No.

Pastor Jeff: Dear Heavenly Father, as we return to school, we look to your eternal...
Billy Sparks: [stands] I pledge allegiance to the...
Pastor Jeff: Billy, it's not the pledge.

Mary: Hey, Brenda.
Brenda Sparks: She didn't want you to walk her in?
Mary: No. How about Billy?
Brenda Sparks: Oh, I walked him in. Found his homeroom. Explained that "homeroom" is different than his room at home. Still not sure he gets it.
Mary: Tough day.
Brenda Sparks: Yeah.
Mary: You want to get some coffee?
Brenda Sparks: I was thinking vodka, but coffee will do.

Sheldon: Dr. Linkletter.
Dr. Linkletter: Sheldon. How wonderfully early it is to see you. If you've come by for a snack, I picked you up some crackers shaped like fish.
Sheldon: I just wanted to let you know that I don't need you to babysit me. I'm perfectly self-reliant.
Dr. Linkletter: Excellent. I'm not very comfortable around children, even with your level of maturity. How old are you? Six? Seven?
Sheldon: Eleven.
Dr. Linkletter: I see. Then it's good I kept the receipt for this bottle of bubbles shaped like a bear.
Sheldon: I should get going. My philosophy class starts in a few minutes.
Dr. Linkletter: Ah, yes, the great thinkers. Socrates, Plato. Speaking of which, I got you some Play-Doh.
