TEXT: Scene: The apartment. Sheldon: Clarify something for me. Isn't the point of a communal meal the exchange of ideas and opinions? An opportunity to consider important issues of the day? Leonard: It is. You just kind of put a damper on things when you said, the next person I see talking with food in their mouth will be put to death. Sheldon: Well, we could argue about who said what all night long, but to set things back on course, I will propose a new topic of conversation. Leonard: Great. Sheldon: What is the best number? By the way, there's only one correct answer. Raj: Five million, three hundred eighteen thousand and eight? Sheldon: Wrong. The best number is 73. You're probably wondering why. Leonard: No. Howard: Uh-uh. Raj: We're good. Sheldon: 73 is the 21st prime number. Its mirror, 37, is the 12th, and its mirror, 21, is the product of multiplying, hang on to your hats, seven and three. Eh? Eh? Did I lie? Leonard: We get it. 73 is the Chuck Norris of numbers. Sheldon: Chuck Norris wishes. In binary, 73 is a palindrome, one-zero-zero-one-zero-zero-one which backwards is one-zero-zero-one-zero-zero-one, exactly the same. All Chuck Norris backwards gets you is Sirron Kcuhc. Raj: Just for the record, when you enter five million three hundred eighteen thousand and eight in a calculator, upside-down it spells boobies. Leonard: Remember when you were wondering why the girls didn't want to eat with us tonight? Howard: Yeah, I get it now. Scene: A bar. Penny: I love your little heart locket, Bernadette. Bernadette: Oh, thanks. Howard gave it to me. It's the cutest thing. Every time I have dinner with his mom, the next day I get jewellery. Amy: Did you know that the iconic Valentine's heart shape is not actually
SUMMARY:
Amy meets Penny's ex-boyfriend Zack and experiences sexual arousal. She later discusses her symptoms with Sheldon, though Sheldon prefers to assume that Amy has contracted an alien parasite. Later, when Sheldon discusses Amy's situation with Penny, she tells him that there is "something" he could do about Amy's "urges", meaning that he should have coitus with Amy, but Sheldon assumes that she meant Amy and Zack should have coitus. He arranges for them to meet again, but Amy discovers that Zack is not very intelligent, solving the problem. Meanwhile, Howard and Raj argue about, if they both acquired superpowers, which of them would be the sidekick. They try to settle the issue in a wrestling match refereed by Leonard, but they merely circle around threatening each other.
