- Dr. Isobel "Izzie" Stevens: [Standing in the bathroom, outside the shower, where George is] I reminded you before you went.
- Dr. George O'Malley: I forgot when I got there.
- Dr. Isobel "Izzie" Stevens: No.
[She opens the shower door]
- Dr. Isobel "Izzie" Stevens: No, you were so passive aggressive!
- Dr. George O'Malley: Naked! I am naked in the shower!
- Dr. Isobel "Izzie" Stevens: [Closes the shower door] Just tampons, George! I really needed tampons. God!
[Meredith enters the bathroom]
- Dr. Isobel "Izzie" Stevens: I'm not riding in the same car as him.
- Dr. Meredith Grey: [Looks at Izzie, who is standing in her "Hello Kitty" underwear] Unless you're going like that, you're not riding with me either. Where are the tampons?
- Dr. Isobel "Izzie" Stevens: He didn't buy them.
- Dr. Meredith Grey: [To George] You didn't buy them?
- Dr. George O'Malley: Men don't buy tampons!
- Dr. Isobel "Izzie" Stevens: [Opens the shower door again, and George falls over] You know what? You're gonna have to get over the whole man thing, George! We're women! We have vaginas! Get used to it!
[She walks out of the bathroom, leaving George lying on the floor of the shower]
- Dr. George O'Malley: I am not your sister!
[He slams the shower door]
