Quotes

 * Leonard: [to Sheldon, Howard, and Raj, who have come to assist him in getting money that Penny's ex-boyfriend owes her] Okay, is everyone clear on the plan?
 * Howard: Yes. Koothrapalli's going to wet himself, I'm going to throw up, Sheldon's going to run away, and you're going to die. Shall we synchronize our watches?
 * Leonard: Excuse me, there are four of us and one of him.
 * Sheldon: Which means his triumph will be even larger. Minstrels will write songs about him.


 * Penny: Oh, Leonard. If we moved in together, I wouldn't be able to keep my hands off of you.
 * Leonard: Really?
 * Penny: And you thought my acting classes were a waste of money.

Critics
"The Big Bang Theory  feels like a show totally happy with who it is and where it is. The dialogue is crisp and silly in equal measure. Everything flows from the well established geeky world which the guys live in and well performed. The show is reliably funny, usually enjoyable and clearly capable of so much more." - The TV Critic's Review

Trivia

 * When Leonard asks the guys what they are doing, Rajesh says that they are on a quest to the Valley of Fire to acquire the Sacred Crown. The goal of the real board game, "Talisman: The Magical Quest Game, 4th Edition," is to reach the center area, called the Valley of Fire, and to acquire the Crown of Command. This is the third appearance of the game, following first season episodes "The Peanut Reaction" and "The Tangerine Factor".
 * The last time that Penny's former live-in boyfriend is seen.
 * In fact, there is a solution to the "movie problem" at the beginning of the movie. The theater screening the movie at 7.40 pm (one of the cinemas Sheldon did not eliminate) is much closer to one of the restaurants Raj pointed at when suggesting his  solution than the theater he was referring to. It also screens the movie twenty minutes after that theater.
 * Sheldon keeps a daily log of social interactions. This is easily possible for him due to his ; a particularly revealing example of his complete recollection is in "The Staircase Implementation", when he says, "I know what my mother said on March 5, 1992."
 * If one assumes this episode takes place in (see airdate), then Sheldon drinks hot chocolate in a month with an "r" in it, consistent with his so-called "whimsy" in "The Lunar Excitation".
 * Last appearance of Penny's former boyfriend and roommate Kurt.
 * At the end of the episode, Sheldon created a song about Leonard and his act of bravery and honor:
 * There once was a brave lad named Leonard.


 * With a fi-fi fiddle dee-dee.


 * He faced a fearsome .


 * While Raj just wanted to pee.
