Big Bang Theory Quote
Raj: You guys know the new discovery class missions that NASA's been working on?
Howard: Yeah.
Raj: Well, they're looking to include a message from Earth in case one of them is encountered by alien life.
Leonard: When I encountered alien life, I discovered that the key thing was not to sit in its spot.
Sheldon: You can't breathe our air without an inhaler. He's allergic to Earth nuts, but I'm the alien.
