Stuart: Do you hear yourself when you say these things?

Penny: What do you mean new roommate? What happened to Leonard?
Sheldon: The same thing that happened to Homo Erectus. He was replaced by a superior species.
Raj: I'm the new homo in town.

Howard: Look at this cute picture of Halley in the bath.
Leonard: Aw, that's great.
