Mary: You want to get comfy on the couch and watch your Star Trek tapes?
Sheldon: No, thank you.
Mary: I know what'll make you feel better. [singing] Soft kitty, warm kitty Little ball of fur Happy kitty Sleepy kitty Purr, purr, purr Soft liar, warm liar Little ball of fib Happy liar, sleepy liar Fib, fib, fib. Feel better?
Sheldon: Uh-uh.

Mary: I'm home.
Sheldon: Would you care to explain this letter, which I didn't read but legally know the contents of?

George: So, we agree that the only way this is gonna happen right now is if you stay local.
Sheldon: I can always go away for grad school someday. And truth be told, I don't have the emotional maturity to squish my own bugs.

[on the video tape:]
Sheldon: Hello. I'm Sheldon Cooper, and this is Why Sheldon Cooper Should Go to College. I realize attending college in another state or country is unrealistic at this time. Which is why I'm proposing that I live at home but enroll full-time to continue my studies with Dr. Sturgis at East Texas Tech. I firmly believe that I'm ready for this next step in my academic life. But don't just take it from me...

[on the "Why Sheldon Cooper Should Go to College" tape:]
Sheldon: Sheldon Cooper, ready for college, ready to change the world.
George: Cut.
Sheldon: If that doesn't convince her, I don't know what her problem is.

Kimberly: We're here with the Cooper family. Mary, George and eleven-year-old Sheldon, who's going to be Medford High School's valedictorian. Mom and Dad, you must be so proud.
George: Oh, very proud.
Mary: But we're proud of all of our children.
Sheldon: She has to say that.

Joaquin: The problem is we've lost control. This is Frankenstein's monster.
Sheldon: You say that like it's a bad thing.
Joaquin: What?
Sheldon: To reanimate life was an incredible scientific achievement. The real bad guys in the story are the ignorant villagers.
Joaquin: You were on the monster's side?
Sheldon: Unfairly hounded for being different? You betcha.

Missy: 95, 96, 97. 99, 100.
Sheldon: You missed 11 numbers.
Missy: I don't need to be good at math. I have beautiful hair.
Sheldon: That's the saddest thing I've ever heard.

Mary: So how's it going?
Sheldon: Well, the principles in the book didn't work for me at all. Although Dad does like being called George over and over again, so you might give that a try.

Sheldon: Mom, what do you know about the drug Prozac?
Mary: Not much. Supposed to make people happier. Why?
Sheldon: I was just thinking some of my teachers might benefit from it.

Mary: Hey, here's an idea. Why don't you invite your new buddy over for dinner?
Sheldon: Why?

Sheldon: My mother asked me to ask you if you'd like to join us for dinner.
Tam: Why?
Sheldon: I was hoping you'd know.

Sheldon: (to George Sr.) Why would you think you knew his mom?

Tam: I don't understand why it didn't launch.
Sheldon: Me, neither. Evil Nazi scientists did it 50 years ago. How hard could it be?

Sheldon: Is this man gonna make me eat solid foods?
Mary: No, he just wants to talk to you about it.
Sheldon: Did you tell him I have a lot to accomplish in my life and cannot afford to be killed by an unchewed sausage?
Mary: Not in those exact words.
