Episode Quotes

Amy: This is an easy one. You love this guy.
Sheldon: Me.
Amy: Come on. He's an under appreciated genius.
Sheldon: Still think it's me.
Amy: It's not you. Now think, there's a car named after him.
Sheldon: Of course there is. The Mini Cooper because it's me.
Amy: How about this? He's a poor man's Sheldon Cooper.
Sheldon: Oh, Tesla.

Raj: I'm sorry I'm so late. I was on the phone with my mother.
Bernadette: How is she?
Raj: Pretty good. She bought the book "Eat, Pray, Love", and used it to set my father's Mercedes on fire.

Raj: So, what's up with you guys?
Howard: We're just saying all the things we love about each other.
Raj: Oh, like you and I did at couple's therapy?

Sheldon: I've learned that 1 in 700,000 people die from general anesthesia.
Leonard: But do you realize that means 699,999 people don't die?
Sheldon: I suppose that's true. You're such a glass half full kind of guy. I'm going to miss that.

Amy: It's sweet that you care about him so much.
Sheldon: I do. And I wouldn't be able to forgive myself if something happened to him, and I wasn't at his bedside to say "I told you so".

As Sheldon and Amy play a game in the apartment, Leonard and Penny return from the doctors. Leonard has been diagnosed with a deviated septum and has elected to have minor surgery to correct it. Sheldon is immediately concerned and doesn't want his friend to have risky surgery. Amy points out that Sheldon has often complained about Leonard's snoring, but Sheldon claims to be used to it now.

Later that night, Sheldon is watching Leonard snoring when he suddenly wakes up. Sheldon is worried that Leonard will die during the surgery. Elsewhere, Raj is having dinner with Howard and Bernadette in their apartment and discussing getting a gift for his parents' fortieth wedding anniversary.

The next day, Leonard arrives home to find Sheldon with a whiteboard listing all the possible ways Leonard's surgery could go wrong. Leonard understand his friend's concern but promises he won't die. Since the surgery is a week away, Leonard promises to think about it. Howard goes to Raj's apartment to hang out, finding Raj on the phone to his father. Raj learns his parents have separated and says it's okay as long as they're happy, but he breaks down when he hangs up the phone that he comes from a broken home.

Leonard and Penny are filling in forms at the hospital, having lied to Sheldon that they were going to a pool. As Amy drives Sheldon, he gets suspicious about where Leonard and Penny really went, leading Amy to confess Leonard is actually getting the surgery. Sheldon demands to go to the hospital for Leonard.

Back at the hospital, a minor earthquake causes the lights to go out. A concerned Sheldon worries that his friend's sinus operation has now turned in to a lobotomy. As Sheldon runs to find Leonard, he crashes into a glass door and falls to the great. Howard and Bernadette are discussing their relationship in their apartment. They don't want to keep things bottled up like Raj's parents , so they decide to start telling each other what they like, and eventually what they don't like about each other.

Sheldon and Leonard are sitting on their couch in their robes with bandages on their noses. Penny decides to take a picture for this year's Christmas card. Leonard apologizes for not telling Sheldon about the surgery, but says he was worrying about nothing. Sheldon lists all the possible post-surgery complications that could still affect Leonard. Penny and Amy realize how much Leonard means to Sheldon. Sheldon shows Leonard the urn he ordered for him in case he didn't make it.
