Dr. Isobel "Izzie" Stevens : [Christina has one of Burkes surgery caps, which he feels he needs to operate and refuses to give it to him. Izzie find out he's about to operate on Denny] Now are you going to give it to him or am I gonna physically take it from you?
Dr. Cristina Yang : [Incredulously] Are you threatening me?
Dr. Isobel "Izzie" Stevens : I swear to God Cristina. I like you. I really do. But I grew up in a trailer park and I am not above kicking your pampered little Beverley Hills ass.
Dr. Isobel "Izzie" Stevens : And I do mean *physically* kicking your ass.
Dr. Cristina Yang : You want me to pee in front of you? Is that what you want?
Dr. George O'Malley : You have it on you.
Dr. Cristina Yang : Oh, really? You want to go there?
Dr. George O'Malley : I want to go there.
Dr. Cristina Yang : So what are you going to do, Bambi? Take it from me.
Dr. George O'Malley : Burke said to do whatever I have to do and I am going to do whatever.
