Big Bang Theory Quote
Zack: One question. How can you be sure it won't blow up?
Leonard: The laser?
Zack: The moon!
Sheldon: See, now this is a man for Penny.
Leonard: That's a great question, Zack!
Sheldon: No, it's not!
Penny: Sheldon, play nice.
Sheldon: Well, it's not a great question! How could someone possibly think we're going to blow up the moon? That's a great question.
Leonard: (to Zack) Don't worry about the moon. We... , we set our laser to stun.
