Quote from Kramer in The Stall
Jerry: Oh, you think she's Erica, the phone-sex woman? Kramer: Jerry, that voice is tattooed on my brain, it's her. I'm telling you, it's her! Jerry: Oh, you're crazy. Kramer: Am I? Or am I so sane that you just blew your mind? Jerry: It's impossible! Kramer: Is it? Or is it so possible that your head is spinning like a top? Jerry: It can't be! Kramer: Can't it? Or is your entire world just crashing down all around you?
