Sheldon on Messages

"You have to check your messages. The leaving of a message is one half of a social construct, which is completed by the checking of the message. If that contract breaks down, then all social contracts break down, and we descend into anarchy!"

Sheldon on Sex

"I'm quite aware of the way humans usually reproduce, which is messy, unsanitary and involves louds and unnecessary appeals to a deity."
