Episode Notes

  • The title refers to Sheldon's attempts to improve his brain function by performing new activities.


Penny: I didn't know you could drink while you were breastfeeding.
Bernadette: Yeah, they say the yeast in beer helps with milk production.
Amy: I'm pretty sure that's a myth. Let me check.
Bernadette: Ruin it for me, and I'll break this glass over your head.

Penny: You want food?
Bernadette: Yeah, breastfeeding burns, like, 5,000 calories a day. (To Amy) Do not touch that phone!

Zack: Do you have a bodyguard to keep spies away?
Leonard: I have Sheldon, that keeps most people away.
Zack: I miss that guy. He's like the Swedish Chef Muppet. I don't know what he's saying, but he's funny.
Leonard: Oh, I know what he's saying, and he's not, he's not funny.

Bernadette: So you wanted to learn something physical and you came to Howard Wolowitz?
Howard: Hey, the circus arts are very physically and mentally demanding. Have you ever tried to juggle?
Bernadette: Yes, I'm juggling my love for you and my embarrassment of you right now.
Howard: And it's hard, isn't it?

Sheldon: Physicist, baker, lover, what can't I do?
