Quotes (34)

Bernadette: You better find my husband's mother, 'cause one way or another we're walking out of this airport with a dead woman.

Howard: I'm sorry I didn't take you to the airport. I just want you to know I'll never forgive myself for being so selfish. And I promise to keep you close for the rest of my life.
Bernadette: Oh, no, that thing's gonna end up in my bedroom.

Howard: Your entire job is to find lost luggage and you've narrowed down the location of my mother to the planet Earth?

Penny: Do you want to stop? I know you have trouble with eye contact.
Sheldon: Well, you have a brown fleck in your right iris that looks like a Formula 1 race car, so I'm just concentrating on that. Plus it's easier around people I'm comfortable with.
Penny: Oh, sweetie, I'm comfortable around you, too.
Sheldon: Of course you are. I'm warm and soothing. I'm like a human bowl of tomato soup.

Amy: I just read about an experiment designed to see if you can make two people fall in love in a matter of hours.
Leonard: That doesn't sound right. My research has shown it takes three to five years of shameless begging.
Penny: Honey, neither of us comes off good in that story.

Recap

As the gang eat dinner in the apartment, Amy mentions an experiment which aimed to see whether people could fall in love in a matter of hours by sharing intimate details and staring into each other's eyes. Sheldon thinks the research is nonsense, but his scientific curiosity leads him to volunteer to test it out. Penny, who is surprised that Sheldon would be comfortable opening up to somebody, offers to do it with him.

After Sheldon and Penny go to her apartment for the experiment, Raj is surprised Leonard and Amy are so calm about their partners testing whether they can fall in love with each other. Leonard offers to do the experiment with Amy, but her rude response to one of his answers puts an end to that. In search of something else to do, Raj, Amy and Leonard agree to meet up with Emily. Elsewhere, after landing in Los Angeles following Mrs. Wolowitz's funeral, Howard and Bernadette are horrified to find the airline may have lost the suitcase containing his mom's ashes.

After Leonard, Amy and Raj pick up Emily, she suggests they spend the night in an "escape room" where they must quickly complete a series of puzzles to escape a "zombie". Back at Penny's apartment, she and Sheldon continue the relationship test. After telling each other their ideal dinner date guest (Sheldon's being Sheldon and Penny's being Robert Downey, Jr.), they move on to describing their perfect day. They both notice each other's perfect day doesn't seem to include their partners, Leonard or Amy. Meanwhile, Howard is told that his missing suitcase did arrive in Los Angeles, but could now be anywhere in the world.

As they continue their relationship test, Penny tells Sheldon she wishes she could be as smart as the others are. Sheldon admits she has intelligence he is envious of, telling her how he struggles to read people properly and doesn't know when they're laughing with him or at him, or when they're having a bad day or they're mad at him. Penny says she wishes she could make things better for Sheldon. At the airport, Howard refuses to leave until they track down his mother's ashes. Howard reveals that he feels guilty for not driving his mom to the airport for her trip, telling her he was too busy. Seeing her husband upset, a scary Bernadette approaches the airline staff to insist they find the suitcase.

Leonard, Amy, Raj and Emily are disappointed that they completed the puzzles so quickly after spending $200 dollars to visit the escape room. Elsewhere, as Sheldon and Penny continue their test over some food, Penny asks Sheldon what he would regret not having said if he were to die today without being able to communicate with anyone. Sheldon tells her there would be something satisfying about dying on his birthday. Penny is surprised to learn it's Sheldon's birthday, which has remained a secret as he hates presents and surprise parties. Penny promises not to tell anyone about his secret.

Back at the airport, the airline has finally found Howard's suitcase. When Howard gets hold of his mother's urn, he apologizes to his mom for not driving her to the airport, promising he'll keep her close to him from now on. Meanwhile, after finishing their test, Sheldon and Penny try to stare into each other's eyes for four minutes. As they do, Penny asks Sheldon if he wants to stop as she knows he has trouble with eye contact. When Sheldon tells Penny he's comfortable around her, Penny says she feels he's like a younger brother to him. Penny is amazed it's been almost eight years since she first met Sheldon and Leonard, and she can't remember her life without them.

After the timer goes off and they stop gazing into each other's eyes, Sheldon and Penny both agree they are not in love following their experiment. After Penny walks Sheldon back to his apartment, he is taken by surprise as his friends jump out to wish him a happy birthday.

I was allways a lenny fan but tbbt writers continue to push penny into a different partner. that she doesn't even mention leonard as part of her perfect day speaks volumns. I never thought i'd say this but they need to split them and let leonard find a true love. they created penny as a person who isn't worth the effort.

With the unfortunate passing of Leonard Nimoy, the hero of Sheldon, Sheldon should do some type of tribute to Spock. And since that Sheldon has DNA from Leonard Nimoy, you could have Sheldon thinking about cloning.
