Raj: I'm just saying that after everything you've been through, you get to look into each other's eyes and say "I love you." And that's beautiful.
Leonard: Actually, to this day, she's never really said it.
Raj: Oh, Penny. That's ridiculous. You know you love him. You, you look him in the eyes and you say it.
Penny: Raj.
Raj: Oh come on, you know you want to say it. Say it. Say you love him. Say it!

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Mrs. Wolowitz I'm not going near that fakakta thing. I'll catch a computer virus.
Howard: You can't catch a computer virus.
Mrs. Wolowitz Oh, so now you're an astronaut and a doctor?

Amy: If Sheldon proposed to me during sex, my ovaries would grab onto him and never let go.

Sheldon: Amy, when I look in your eyes and you're looking back in mine, everything feels not quite normal. Because I feel stronger and weaker at the same time. I feel excited and, at the same time, terrified. The truth is, I don't know what I feel, except I know what kind of man I want to be.
Amy: Sheldon, that was beautiful.
Sheldon: I should hope so, that's from the first Spider-Man movie.
Amy: I'll take it.
