Leonard: You're too close to it, but Amy has had a huge impact on your life.
Sheldon: You're right. Without realizing it, I have allowed that women to alter my personality.
Leonard: Sheldon, you didn't have a personality. You just had some shows you liked.

Sheldon: I've changed. Like the frog who's put in a pot of water that's heated so gradually, he doesn't realize he's boiling to death.
Penny: Or you're the frog who's been kissed by the princess and turned into a prince.
Leonard: Or you're just a tall, annoying frog.

Leonard: You make a lot of sense. I like this table and I'm getting it.
Penny: Really, this one?
Leonard: That one.
*Penny nods*
Leonard: Damn right I like that one.

Penny: Ooh, this one looks nice.
Leonard: No, Sheldon doesn't like reclaimed wood.
Penny: Why not?
Leonard: He's afraid the original owners will come back.

Leonard: Cinnamon, guess who just did it "human-style".

Leonard: Ooh, flowers and chocolates? Somebody's trying to get me out of my panties.

Penny: Aw, jewelry. Oh my God, Lakers tickets!
Leonard: It gets better. Instead of me you can take someone who will actually enjoy it.
Penny: You are the best boyfriend ever.
Leonard: Seriously, please don't make me go.

Leonard: I'm not sure it's a good idea to take Penny to where wine comes from.

Leonard: I haven't seen him this stuck since he tried to figure out the third Matrix movie.

Leonard: Hey, can we talk?
Penny: We can, but the part of Penny might get cut.

Raj: Since Sheldon isn't coming to Comic Con with us, why don't we dress up as some sort of trio?
Leonard: Or we could just be the Fantastic Four and tell everyone that the Invisible Girl is standing right next to us.

Raj: Does he sound like a criminal?
Howard: What do you mean?
Raj: You know, did he say things like "youse guys" or "listen here, say".
Leonard: Yes, he's late because he's on his way here from 1940.

Sheldon: Gentlemen, I am one step away from securing a huge guest for my convention.
Leonard: Does that step include chloroform and a roll of duct tape?

Howard: I already found a guy online who is willing to sell.
Sheldon: How do you know this isn't a sting operation set up by the Comic-Con police?
Leonard: The same way I know the people in the TV set can't see me.

Raj: Do you support this?
Leonard: Of course I do. She's a great actress. I'm proud she's taking this risk.
Amy: That's nice.
Leonard: You bought that!? Great! I gotta call her before I forget how I said it.
