Sheldon: So, spring break is just around the corner.
Dr. Linkletter: I'm counting the days.
Sheldon: Me, too. Have you reserved the lab yet?
Dr. Linkletter: Why would I do that?
Sheldon: Without the distraction of classes, you and I can really buckle down and get some work done.
Dr. Linkletter: I won't be here, Sheldon. It's my break, too.
Sheldon: Where are you going?
Dr. Linkletter: I'm not telling you where I'm going, Sheldon.
Sheldon: Why not?
Dr. Linkletter: Because I'll be happy, and I want to stay that way. You're in college. You should be taking spring break as well.
Sheldon: And do what?
Dr. Linkletter: Traditionally, you would congregate with your peers and make bad decisions.
Sheldon: But I'm a kid.
Dr. Linkletter: Then perhaps a game of Duck, Duck, Goose.
Sheldon: Sarcasm?
Dr. Linkletter: No.
Sheldon: Geez, you really do need a break.

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.

Ms. Hutchins: I don't know.
Mary: Trust me, the men are gonna be lining up.
Ms. Hutchins: Well, they haven't been so far, and I've been basically giving it away.
Mary: That's your business really.

Sheldon: Mom, I know what I want to do for spring break. What happened to your face?
Mr. Lundy: Told you, people take notice.
Mary: This is for my new job.
Sheldon: Is your new job fighting Batman? Because you look like The Joker.

Nathan: Hey, you made it. [Star Trek salute]
Sheldon: It would have been illogical not to.
Nathan: [deep voice] Well, you're going to have a blast.
Sheldon: I know this is un-Spock-like, but I can't stop smiling.
Mr. Givens: [climbs aboard] [British accent] There you are, dear sir. Let's get this pusillanimous bucket of nuts and bolts on the road. [applause and cheering] We have a comic-con to get to!
Sheldon: Mr. Givens?
Mr. Givens: Oh, the pain.
