Sheldon: Oh, Leonard, thank you again. We love the gift.
Leonard: Aw. [After Sheldon leaves] Does he know what it is?
Howard: No, not even close. He thinks it's a clue to a scavenger hunt.
Leonard: (laughs) So, so happy.

Leonard: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Amy: Well, Leonard and Penny are our best friends. They know us better than anyone. They said it's the perfect gift. We must be missing something. You don't think it's a marital aid, do you?
Sheldon: Don't be silly. Amy, how is this big glass shaft going to aid our marriage?

Amy: Let's just go to sleep. We'll look at it in the morning with fresh eyes, and maybe it'll come to us.
Sheldon: Fine.
Amy: Or we go tear apart that box and look for a clue.
Sheldon: Staying up past my bedtime and solving mysteries? Who knew married life could be this good?

Sheldon: Howard, I don't often say this, but, good, you're here.
