Georgie: Yeah, sure, I remember Tam, Sheldon's little Vietnam buddy. The two of them were always running around together.
Leonard: So, what happened?
Georgie: What do you mean?
Leonard: Well, I mean, Sheldon never talks about him. They haven't spoken in years. He wasn't at the wedding.
Georgie: He wasn't? All right, well, this is embarrassing, 'cause I had a long conversation with someone who I thought was Tam.

Georgie: Picking on him? Is that what he told you?
Leonard: Well, what about the time you threw away his Halloween costume?
Georgie: Well, yeah, 'cause he was gonna dress as some girl scientist.
Leonard: Madame Curie?
Georgie: Oh, I didn't know she was a madam.

Georgie: You went away to college after Dad died. Who do you think took care of everything?
Sheldon: Mom did. Mom always took care of everything.
Georgie: Mom was a mess, Missy was a dumb teenager. I had to look after both of 'em.
Sheldon: I talked to Mom all the time. If she was upset, she would have told me.
Georgie: She was protecting you, you idiot, just like everyone always does.
Sheldon: If things were bad, then why didn't you tell me?
Georgie: Because I was protecting you, too. (sighs) You're my baby brother, Sheldon. I know life has been hard for you, but that don't mean it's been easy for the rest of us.

Georgie: Hey, you've reached George Cooper. Please leave a message. Unless this is Sheldon again, in which case, please try me on my other number, 1-800-suck-it.

Amy: I tried to ask him about it, and he invoked section three, article five of the marriage contract: beeswax comma none of your.

Bernadette: Look, I think that's LeBron over there.
Penny: James?
Bernadette: No, LeBron Kershenbaum.

Amy: Who's Tam?
Sheldon: He was my best friend in the whole world growing up.
Amy: Really? Why have I never heard you mention him before?
Sheldon: Oh, of course I have. I'm sure I've mentioned him, like, five times this week.
Amy: I don't think you have.
Sheldon: Tam! Tam! Tam! Tam! Tam! There, it's only Thursday.
Amy: I didn't just drink the crazy milk, I bought the crazy cow.
