Quote from : The Search for Signs of Intelligent Life in the Universe Book

Did I tell you what happened at the play? We were at the back of the theatre, standing there in the dark, when all of a sudden I feel one of 'em tug at my sleeve, whispers, "Trudy look!" I said, "Yeah, goosebumps. You definitely got goosebumps. You like the play that much?" They said it wasn't the play that gave 'em goosebumps, it was the audience! I'd forgot to tell them to watch the play; they'd been watching the audience! Yeah, to see a group of people sitting together in the dark, laughing and crying at the same things...well that just knocked 'em out! They said, "Trudy, the play was soup, the audience, art." So they're taking goosbumps back with 'em into space. Goosebumps! Quite a souvenir. I like to think of them out there in the dark, watching us. Sometimes we'll do something and they'll laugh. Sometimes we'll do something and they'll cry. And maybe, one day we'll do something so magnificent, the whole universe will get goosebumps.
