Big Bang Theory Quote
Howard: Ooh, 8:30. You and Penny decide to go out and paint the town beige?
Leonard: You're 30 years old and you live with your mother!
Raj: I guess it didn't go well.
Sheldon: Now, we don't know that. Not to a certainty. All we know is that Leonard is home.
(Leonard groans loudly from his room)
Howard: How about now?
Sheldon: Again, not enough evidence. For all we know, he's being murdered.
