Big Bang Theory Quote
Leonard: Listen to me. We can't do anything until you do your part. So get up in front of this whiteboard and do it!
Sheldon: I can't.
Leonard: Yes, you can.
Sheldon: No, I can't figure out the math. I've been wracking my brain for days. I've got nothing.
Leonard: Seriously?
Sheldon: I can't do it. I'm not as smart as I think I am. I'm so sorry. This is all my fault.
