Quotes (17)

Leonard: You'll never guess what just happened.
Sheldon: You went out in the hallway, stumbled into an inter-dimensional portal, which brought you 5,000 years into the future, where you took advantage of the advanced technology to build a time machine, and now you're back, to bring us all with you to the year 7010, where we are transported to work at the think-a-torium by telepathically controlled flying dolphins?
Leonard: Penny kissed me.
Sheldon: Who would ever guess that?

Sheldon: I'd like to go over some proposed changes to the roommate agreement, specifically to address Penny's annoying personal habits.
Penny: Oh my God! What personal habits?
Sheldon: I have a list. FYI overuse of the phrase "Oh my God" is number 12.

Sheldon: I don't care for novelty editions of Monopoly. I prefer the classics: regular and Klingon.
Howard: Actually, Indian Monopoly is just like regular. Except the money is in rupees and instead of hotels, you build call centers. And when you pick a chance card, you might die of dysentery. Just FYI, that was racist.

*Leonard is kissing Penny, and Penny's dad enters*
Penny: Come on, honey, not in front of my dad.
Penny's dad: Relax, I've seen her do a lot worse with a lot stupider.

Howard: Don't be oversensitive. He's calling you illiterate, not your race.
Raj: Oh, okay. Good.

Penny calls Leonard "sweetie" and kisses him, then slams the door in his face, confusing Leonard. After Leonard returns to his apartment, he tells the guys about what just happened with Penny.

Penny comes over to Leonard's apartment to explain that she told her father they had got back together, since he was the first boyfriend her father approved of. Wyatt comes to the apartment and invites Leonard to join him and Penny for dinner. Elsewhere, Bernadette and Howard join Raj as they spend the night monitoring a telescope. Although Raj isn't best pleased, Howard brought Bernadette as he'd like his best friend and girlfriend to bond.

On their way back from dinner, Wyatt is telling stories to Leonard about Penny's ex-boyfriends. Leonard is pleased to hear her dad describe him as a keeper. When Sheldon observes Penny and Leonard kissing goodnight, Sheldon fears they are back together. Back at Raj's lab, they are playing Indian Monopoly when Bernadette and Raj start talking about how bad Howard's jokes are. They then proceed to make fun of Howard's mom. Back at the apartment, Sheldon wants Leonard to set up an escrow account to pay for Penny's expected infractions now they're back together.

Later, Wyatt is yelling at Penny, telling her how upset he is that she lied to him. When Penny leaves the room, Wyatt begs Leonard to not give. up on Penny. He uses reverse psychology by yelling at Leonard to make Penny want him more.

When Leonard returns to the apartment, Sheldon has stayed up all night preparing an extended roommate agreement. Leonard tells Sheldon that they're not back together, causing Sheldon to throw the paperwork up in the air.

@magooglie, Penny was absent from two episodes as the actress Kaley Cuoco had injured herself in a horseback riding accident.

each episode is more like FRIENDS, just my opinion with much entanglement between Penny and Leonard, I hope this has a good finish by the end of the season, the series is spectacular and has many hilarious moments that do not lose hope course ...
