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.
