Kramer: My face is all craggly, it's crinkly!
Jerry: It's from all that smoke. You've experienced a lifetime of smoking in seventy-two hours. What did you expect?
Kramer: Emphysema, birth defects, cancer. But not this. Jerry, you know, my face is my livelihood. Everything I have I owe to this face. It's my allure, my twinkle.
Jerry: And your teeth, your teeth are all brown.
Kramer: Look away, I'm hideous.
