Leonard: If you want me to object at your wedding, just give me one of these. (taps on his nose)

Sheldon: I remember the song! It's called "Darlin'" by the Beach Boys! Oh, thank goodness! I'm not crazy! I don't have to take a pigeon as my bride!
Leonard: There goes our shot at him living on the roof.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Leonard: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

Bernadette: One of the great things about being pregnant is drinking cranberry juice out of a wineglass and watching people freak out.

Sheldon: I call this meeting of the Council of Sheldons to order. Let's take roll. Science Sheldon?
Science Sheldon: Present.
Sheldon: Texas Sheldon?
Texas Sheldon: Howdy.
Sheldon: Fanboy Sheldon?
Fanboy Sheldon: Greetings.
Sheldon: Germaphobe Sheldon?
Germaphobe Sheldon: Say it, don't spray it.
Humorous Sheldon: Where's Jock Sheldon?
Sheldon: Not the time, Humorous Sheldon!

Sheldon: Why can't there just be one week each month for famous people to die?
Amy: Well, they've already arranged to die in threes. What more do you want from them?
