Big Bang Theory Quote
Penny: You don't even like people touching you. How are you gonna have sex?
Sheldon: Why on earth would we have sex?
Penny: Oh, honey, did your mom not have the talk with you? You know, when your private parts started growing?
Sheldon: I'm quite aware of the way humans usually reproduce, which is messy, unsanitary, and based on living next to you for three years, involves loud and unnecessary appeals to a deity.
Penny: Oh, God.
Sheldon: Yes, exactly.
