Leonard, why do you always do this? Listen to me, you are the one that I'm with. You know that I love you. So, will you please relax, because you are driving me crazy.
Leonard: Who you talking to?
Penny: Just this guy I met at school.
Leonard: We're still dating, right?
Sheldon: Get the Mad Hatter on the horn, I'm having a tea party.
Penny: You might want to pace yourself.
Sheldon: I drink tea all the time. I think I know what I'm doing.
Penny: Far be it from me to criticize a man with a full pubis.
Hey, this is my paper. And, my perspective is that slavery is bad. Oh, and my professor's black, so I'm pretty sure that's the right answer.
Amy: You have to be the weirdest couple I know.
Penny: Really? You can't think of anyone weirder?
Amy: I can, [whispers] but she's sitting right there.
Sometimes I forget how smart you are.
Penny: You're unbelievable.
Sheldon: I know.
Amy: Looks like something used by Tinker Bell's gynecologist.
Penny: Who I hope for her sake is not Captain Hook.
Penny: I'm just a blonde monkey to you, aren't I?
Sheldon: You said it, not me.
Penny: We're keeping things, you know, homeostasis.
Amy: It's so cute when she tries.
Sheldon: Penny? Please don't hurt my friend.
Penny: That is the last thing I want to do.
Sheldon: Thank you.
Amy: Soon my upper lip will be the same fake blonde as my beautiful best friend.
Penny: Hey, this is my natural hair color - Now.
