Quote from Phoebe in The One Where Joey Moves Out
Rachel: That is not a tattoo. That is a nothing. I finally got her in the chair, he barely touched her with the needle, she jumped up screaming and that was it. Phoebe: Okay, hi. For your information, this is exactly what I wanted. This is a tattoo of the Earth as seen from a great, great distance. It's the way my mother sees me from heaven.
