Martin: Wow, I never knew that.
Frasier: That's the point of this whole experiment, to tell one and other something we don't know about each other, something vulnerable. Now it's your turn.
Martin: OK. Well, about two months ago I was in the basement going through some old pictures of your mother and me. All of a sudden, something flew up in my eye. And when I was trying to get it out, I realized that I could turn my eyelid inside out, the way kids do at camp.
Frasier: That's it? You call that vulnerable?
Martin: It hurt!
