Penny: Hey, where's your fiance?
Zack: Oh, she couldn't make it. She had an emergency.
Penny: Oh, no, what happened?
Zack: I didn't ask.

Amy: What smells so good?
Sheldon: Raj is teaching me to make croissants.
Amy: Is this part of your super-aging?
Sheldon: Yes. Yeah, it seemed daunting at first, but then I realized, it's like the chemistry set I had as a kid.
Only, when your brother eats this, no one has to call Poison Control.

Howard: So the key is, the moment one ball is at the top of its arc, you toss the next one.
Sheldon: Okay, I think I got that.
Howard: Uh, h-hold on. There's an old saying in juggling.
Bernadette: Is it "I'm going to die alone"?
Howard: No, it's "if you want to have fun, start with one." Yours we think, but we do not say.

Sheldon: Just to be on the safe side, am I in any danger of getting juggler's elbow?
Howard: No.
Sheldon: Are you sure? 'Cause I'm feeling a twinge.

Amy: Where did you get it?
Sheldon: Howard said I could borrow it, Bernadette said forever.

Howard: So you told her she was being dumb?
Leonard: No, I told her she was being not smart. Which was dumb.
Raj: Why did you even go to dinner with the guy?
Leonard: We covered this, I'm dumb.

Howard: You know what? I'm with Leonard, this isn't cool.
Leonard: Thank you.
Raj: I disagree. Penny is a strong, independent woman. The more you try to control her, the more she'll push back.
Leonard: So you think it's okay?
Raj: Oh, no, she's gonna leave you for someone, might as well get it over with.

Amy: What are you doing?
Sheldon: I'm returning this stuff to Howard.
Amy: Oh, Bernadette made me promise if you didn't want it, we'd give it to a homeless clown.

Amy: What happened to learning the unicycle?
Sheldon: Oh, I stopped that, it was dumb. Uni, bi, tri, menstrual, all cycles are dumb.
Amy: You said juggling was dumb, too.
Sheldon: Well, it is. If I wanted to hold three things at once, I'd wear cargo pants.

Amy: What are you reading?
Sheldon: This article says the peak age for making a Nobel Prize-winning discovery is 40.
Amy: So?
Sheldon: So, I'm running out of time.
Amy: That's ridiculous, you're a brilliant man. The best years of your life are still ahead of you.
Sheldon: Oh, you have to say that, you're sweet on me.

Amy: Well, if you're really worried about your career, maybe you should consider spending a little less time with video games and comic books.
Sheldon: Hey! I thought you were sweet on me.

Howard: I can't believe you made fun of me all these years while you were a closeted ventriloquist.
Bernadette: Okay, it's not like I wanted to be a ventriloquist. I was in beauty pageants and I needed a talent besides spreading rumors that the other contestants were pregnant.
