Quotes (25)

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

Howard: You gotta like this: the girlfriend, the ex-girlfriend, bonding over your rooty-tooty stinky booty? (All but Leonard laugh)
Leonard: Kill me!
Sheldon: It wouldn't help. The human body is capable of being flatulent for hours after death.

Penny: So that means, you're a doctor, you're a doctor, you're a doctor, you're a doctor and ... Howard you know a lot of doctors.

Since season 4, Penny no longer wears sexily. How she dresses before is to make the shows more interesting to watch.
