Amy: Sheldon, you had no right.
Sheldon: What- I thought you said you were spread too thin. You said that you wished you had more time to focus on our research. I thought I was helping.
Amy: Well, you're not. I mean, I have years invested in this work, and now someone's gonna come in and take it over? I mean, how would you feel if I let Leonard take over your super-asymmetry project?
Sheldon: (laughs) That's funny. Oh, he'd be like a puppy with a microscope.
