Leonard: Oh, hey, Sheldon. We're kind of in the middle of something.
Sheldon: Oh, I won't be a moment. I just need to grab a book off a high shelf, which I can do because I am both tall and smart.
Amy: Sheldon, come home! They don't want to have your baby!
Sheldon: I don't know what you're talking about. Oh-oh, dear, I think I got something in my eye. My piercing, blue eye.
Sheldon: Fine. I've also never had a cavity and I don't have asthma.
