Amy Farrah Fowler
Amy Farrah Fowler, played by Mayim Bialik, is the potential love interest for Sheldon on The Big Bang Theory. Much like Sheldon, she is incredibly smart and socially awkward. Also much like Sheldon, she's not very sexual and not really interested in coitus. Perfect for him really.
Sheldon: Ugh! English pudding. Y-You get yourself all excited for pudding, and here comes a cake with raisins in it. I'm not going.
Amy: You're going.
Sheldon: Why do you hate me?
Amy: I don't hate you. I love you.
Sheldon: Well, you call it love, but it has a lot of raisins in it.
Amy: I have potential for sexual arousal.
Sheldon: A cross we all must bear.
