Penny: Look at that! I discovered a comet! Oh!
Raj: What do you mean you discovered it?
Penny: Well, I'm the one who saw it.
Raj: In my telescope that I positioned. All you did was look into it.
Leonard: Well, you both discovered it. You can put both your names on the registration form.
Raj: Actually, we can't.
Leonard: Why not?
Raj: Because when I filled it out, it asked for name of discoverer, and I put "Rajesh Koothrappali" because because that's who I am, and that's what I did.
