Penny: Well, so how does it work?
Stuart: Ah, well, it shows me all the single women in a five-mile radius who are using the app. If I like the way they look, I hit thumbs up. If I don't, thumbs down.
Bernadette: Oh, what would make you give a girl a thumbs down?
Stuart: First time it happens I will let you know.

Penny: Okay, don't be offended, but what went wrong with you?
Stuart: I guess I assumed at this point in my life, I would be married or in a relationship, or even have a pet that didn't run away or kill itself.
Bernadette: That really happened?
Stuart: I mean, I can't say for sure, but I swear that rabbit looked me right in the eye before it hopped in front of that car.

Stuart: How about those guys on that bench over there? They look pathetic. Maybe we could talk to them.
Raj: That's a mirror.

Stuart: When I was a baby, my mother called me her little possum.
Raj: Are possums cute?
Stuart: Not at all.

Raj (shouting from upstairs window): Hey, Jon Snow. How come your horse has a basket on it?
Stuart: How come your head has your face on it?
Sheldon: They don't wear bicycle helmets in Game of Thrones. You're thematically inaccurate, but I applaud your commitment to safety.
Stuart: Don't you guys have anything better to do?
Leonard: Better than watching a guy in a fur cloak ride a girl's bike? Nope.
Stuart: That's it, you just lost bathroom privileges at the comic book store.

Sheldon: I see what's happening. Sides are forming. Well, if Bernadette's on Amy's team, I pick Howard.
Howard: I'm not taking sides.
Sheldon: Fine. I guess I'm stuck with Raj.
Raj: Really?
Stuart: At least you got picked.

Raj: Dude, if we do this, we're gonna need a cool band name.
Howard: You know, I've actually had one I've been sitting on for years.
Raj: Really?
Howard: It was for this power trio I tried to put together in junior high, but I was short two friends.
Raj: What is it?
Howard: Footprints on the Moon.
Raj: I just got chills.
Howard: So did I.
Stuart: Me, too. But I might have Lyme Disease.

Stuart: Boy, who would've thought when you asked me to move in and help take care of your mom, I'd still be here two years later?
Howard: No one.
Bernadette: Nobody thought that.

Howard: Maybe I'll just hang out here for a while.
Stuart: Great. And you can make fun of me all you want.
Howard: No, that's okay.
Stuart: No, no, no. Go on. I can take it. My feelings, like my extremities, are basically numb.

Raj: Okay, let's have a whiff. Oh. (sniffs) Hmm. Smells like Paco Rabanne.
Stuart: Ooh, you're good. I bought it at a swap meet. It's actually called "Smells Like Paco Rabanne."

Raj: Hey, you should totally get it. In fact, I'll buy it for you.
Stuart: Sold!
Emily: Raj, you don't have to do that.
Stuart: Too late! No returns!

Stuart: Hmm. (looking around at the room)
Howard: What?
Stuart: I just have never been in this room while you're awake.

Bernadette: And how many guys have you gone out with?
Stuart: Please be less than two.
Amy: Three.
Stuart: Damn it.

Bernadette: Yeah, I mean, with you and my parents, she's gonna be fine.
Stuart: Ah, of course she is.
Bernadette: And that day care is great.
Stuart: It is. I went to check it out, and they are very cautious about letting strange men with no kids peek in the windows.

Stuart: I don't mean to be rude, Sheldon, but my life is kinda falling apart right now.
