Big Bang Theory Quote
Penny: (Sheldon has locked himself out of his apartment) I think the emergency key is around here somewhere.
Sheldon: We have a bowl. Our keys go in a bowl. You should get a bowl.
Penny: So, how did the beautiful mind of Sheldon Cooper forget his key in the first place?
Sheldon: I left them in the bowl.
