This morning's argument (I'm as confused as you are by Margot's opening statement):
Margot (staring in mirror): "Ugh. I don't even look like a zombie."
Claire: "I think you do."
Margot: "Claire, no I don't. And anyway zombies don't have heads."
Claire: "They do too have heads!"
Margot: "No, they don't."
Claire: "Well, Michael Jackson has a head in the "Thriller" video."
Margot: "Duh, Claire - Michael Jackson is a fake zombie. Real zombies don't have heads."
