Sheldon: So that's all this day was? A plan to butter me up before delivering bad news?
Leonard: Come on, buddy.
Sheldon: No, I thought we were friends. You asked for a sip of my Icee. If you had your own straw, I might've said yes.

Penny: Sheldon, please, we already feel bad about this.
Sheldon: You know what they don't sell at The Container Store? Something large enough to contain my disappointment.
Although, if anyone did, it would be them.

Howard: We will, we will, percussive shock you.
Raj: We will, we will, percussive shock you.
Sheldon: Buddy, you're a boy, make a big noise, playin' in the street, gonna be a big man someday.
You got mud on your face, you big disgrace.
Kickin' your can all over the place.
I have an eidetic memory. Sometimes it's a curse.

Sheldon: Let's take this problem one step at a time. First, we need to decide whether we're calling it lee-ver or lev-er.
And the sooner we decide it's lee-ver, the sooner we can roll up our slee-ves - and not sle-ves - and get to work.
Leonard: We're going to be here for ee-ver.

Sheldon: Leonard?
Leonard: What?
Sheldon: I am getting too old for this crud.

Sheldon: What was that?
Howard: I think it's a tire.
Sheldon: What if it's banditos shooting at us? What if we get kidnapped? What if we end up in a factory making Bart Simpson pinatas for the rest of our lives?

Raj: Perhaps some of his mojo will rub off on us. Maybe between this and his beach house, we will be inspired to greatness.
Sheldon: I usually don't put too much stock in charms and talismans. However, even I must admit feeling Richard Feynman's butt dent cupping my own bottom that does get the creative juices flowing.
Howard: Hey, I have to return this van. Keep your creative juices in your pants.

Sheldon: Are we all up to date on our yellow fever inoculations?
Howard: You don't need a yellow fever shot to go to Mexico.
Sheldon: You can never be too careful. I got one last year before I went to Epcot.

Raj: What's wrong with Mexico?
Sheldon: Uh, Mariachi bands, wild dogs, beans that jump around because there's a worm inside.

Howard: Calm down. There's a theme to this weekend. We are going to Mexico in Feynman's van to stay at the vacation house Feynman bought with the money from his Nobel prize.
Sheldon: Viva la Imodium. Ay, ay ay!

Sheldon: It's bad enough that I'm being taken against my will. I don't see why it has to be in some hippie's mobile sex dungeon.

Howard: Well, Sheldon, there's something about this van that you're going to find very interesting.
Sheldon: It runs on syphilis?

Leonard: This was Feynman's van? This is so cool.
Raj: Yeah, nothing's been changed since he drove it.
Howard: Bet he picked up a lot of cute grad students in this bad boy.
Sheldon: And talked about physics with them.

Howard: We are going to Me-he-co.
Leonard: Fun! I've never been there.
Sheldon: Leonard, don't be fooled. I'm from Texas. Me-he-co is Spanish for Mexico.

Sheldon: Would you pass the mustard.
Leonard: Sure. Hey, you wanna hear a fun fact about mustard?
Sheldon: Is it that the glucosinolates that give mustard its flavor were evolved by the cabbage family as a defense against caterpillars?
Leonard: Yeah.
Sheldon: Well, that was fun. Good for you, Leonard.
