Quote from Rachel in The One with Ross's Grant
Rachel: All right, fine. You can keep it. As long as you don't mind that she's haunted. Joey: Hey, what? What? Rachel: Well, legend has it, Joey, that she comes alive when you're asleep. She climbs out of the frame and then drags her half-a-body across the floor just looking for legs to steal. And then with her one good hand she slowly reaches up and turns your doorknob. Joey: Get that legless witch out of here!
