Sheldon: Too bad there's not a comic book database so I could search through it and find what I'm looking for.
Dr. Linkletter: Well, CERN has something similar. You can search a database of scientific papers.
Sheldon: But there's no database for comic books.
Dr. Linkletter: You should make one. Somewhere else.
Sheldon: Mmm, sounds like a lot of work.
Dr. Linkletter: Or does it sound like a lot of fun? Go find out.
Sheldon: Do you want to do it with me?
Dr. Linkletter: Only if you share credit, and my name comes first.
Sheldon: Never mind. [exits]
Dr. Linkletter: I knew that would work.

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.

Sheldon: Now, about the telescope room, I was watching Star Trek and it got me thinking...
Dr. Linkletter: Sheldon, searching for life on other planets isn't serious science. Leave that to the tinfoil hat brigade.
Sheldon: But statistically, given the number of stars and planets, it's likely we could find one capable of supporting life. And if we did, it would be the greatest scientific discovery of all time.
Dr. Linkletter: Yes, and if I had fruit on my head, I'd be Carmen Miranda.
Sheldon: I'm not familiar with that reference.
Dr. Linkletter: She sang and danced with fruit on her head.
Sheldon: Why would she have fruit on her head?
Dr. Linkletter: I don't know, in case she got hungry. It's not gonna happen, Sheldon!

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Great.
Sheldon: Do you think you could get me access to the telescope room? I want to search for exoplanets that could support life.
Dr. Linkletter: Are you feeling homesick?
Sheldon: Are you implying that I'm from another planet?
Dr. Linkletter: Yes.
Sheldon: Compliment accepted.

Sheldon: Why would New Mutants be next to New Teen Titans?
Missy: Because they both start with "New"?
Sheldon: But one's Marvel and the other's DC. Would you put Aquaman and Sub-Mariner next to each other?
Missy: I don't know, they could talk about fish.

Adult Sheldon: In the world of collecting, I'm what's known as a completist. For example, I own every gauge of model train from the mighty "G," to the tiny "T." Look at how cute it is, I just want to eat it up. However, the downside of being a completist is when something's missing, it's like an itch you can't scratch, even if you own a complete set of Justice League back scratchers... which I do. In this case that itch was the comic book issue Doom Patrol and Suicide Squad Special #1.

Sheldon: What do you mean, you sold it?
Missy: Somebody gave me money, and I gave them the comic book. That's kind of how things work here.
