Episode Notes

  • The title refers to the two different ways the gang spend the evening: Leonard, Penny, Amy, Raj and Howard at a wine tasting event, while pregnant Bernadette spends the night with Sheldon.

> Sheldon's Spot

After spending an enjoyable evening playing Dungeons and Dragons with Bernadette to get her mind off being pregnant, Sheldon tells Bernadette that any time she wants a break from being "Bernadette the Pregnant", "Bernatrix the Warrior Queen" is waiting. When Bernadette says she might take him up on that offer, Sheldon points out that it's only good until the third trimester as he can't risk getting amniotic fluid on his spot.

Episode Quotes

Zack: Penny?
Penny: Oh, Zack, hi. You guys remember Zack?
Howard: Yeah, hey, buddy.
Amy: Hello.
Raj: Hey.
Zack: Hey, did you two get married?
Penny: We did.
Leonard: Yeah, mmm-hmm.
Zack: To each other?
Penny: Yes.
Zack: Cool. 'cause other than when you broke up with him and dated me, then broke up with me, and then dated me one more time before going back to him, I was always rooting for you two.

Penny: All right, well, let me know if you guys want to go.
Raj: I would love to. I do enjoy the complexity of an aged Pinot noir.
Leonard: I'm sure that would pair nicely with your fried nuggets of chicken.

Amy: Well, it sounds like a nice night. We should go.
Sheldon: Wine again? Yeah, no, thank you. I like my grapes the old-fashioned way, in a juice box.

Sheldon: Well, it makes perfect sense. Because you're an expectant mother, you can't drink alcohol. I don't like to. You can't have sushi. I don't like to. You can't go in hot tubs. I consider them vats of sweaty people soup.
Bernadette: Gee, Sheldon, I dont know.
Sheldon: Oh, come on. Roller coasters, caffeine, runny eggs, I've been avoiding these things all my life. And now, because you're pregnant, you have to.

Leonard: The difference is she's bringing life into the world, and you suck it out.
