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.
Amy: Sheldon, there's something else I've been wanting to say, but before I do, I just... I want you to know that you don't have to say it back.I know you're not ready, and I don't want you to say it just because social convention dictates...
Sheldon: I love you, too.
Amy: You said it.
Sheldon: There's no denying I have feelings for you that can't be explained in any other way. I briefly considered that I had a brain parasite. But that seems even more far-fetched. The only conclusion was love.
Amy: I have potential for sexual arousal.
Sheldon: A cross we all must bear.
