TEXT: MEREDITH: At any moment, the brain has 14 billion neurons firing at a speed of 450 miles per hour. We don't have control over most of them. When we get a chill, goosebumps. When we get excited, adrenaline. The body naturally follows it's impulses, which I think is part of what makes it so hard for us to control ours. (Shot of Izzie in the kitchen, surrounded by dozens of muffins.) IZZIE: That's enough muffins. We don't need all these. No more muffins. (Yet she goes to make another batch.) MEREDITH: Of course, sometimes we have impulses we'd rather not control. (Christina walks into Burke's room and begins stripping off her scrubs, climbing atop his bed in nothing but her red lingerie.) BURKE: what are you doing? CHRISTINA: Just because you cant touch, doesn't mean you can't enjoy. MEREDITH: That we later wish we had. (Burke's parents walk into his room.) BURKE: Mama... Daddy. CHRISTINA: Oh...what... MRS. BURKE: Preston? CHRISTINA: Mama and Daddy!? MRS. BURKE: Is this a new service the hospital is providing? (Christina scrambles to clothe herself.) CHRISTINA: I told you to guard the door. NURSE: I had a code blue. CHRISTINA: I had parents walk in. NURSE: We saved the guy's life. CHRISTINA: Whatever, I want my 20 bucks back. NURSE: Sorry. It bought everyone coffee to celebrate saving the guy's life. CHRISTINA: I want my 20 bucks back! MEREDITH: You know it's not Tyler's fault you're a dirty, dirty stripper. CHRISTINA: You heard. MEREDITH: Everyone heard. Stripper CHRISTINA: Oh you're one to talk. Sleeping with two men. MEREDITH: Wrong. I'm not sleeping with either one of them. Not
SUMMARY:
Cristina makes a bad first impression on Burke's parents and is also surprised to find that he is a "mama's boy". Burke's mother believes that Cristina is too selfish and driven for her son, and is only trying to take advantage of his extensive knowledge of cardiothoracic surgery. Izzie uses baking to cope with her grieving, and bakes hundreds of muffins. After pinning Meredith's panties to a bulletin board, Addison takes a day off from the hospital and spends the day drinking. Due to Addison taking the day off, Bailey has Alex help her in the pit, and they're faced with a teenage patient who has been impaled on a tree branch. A brain tumor patient quizzes Meredith and Cristina over their respective relationships. Webber discovers that Callie has been living in the hospital and tells her she has to leave because of hospital policy. Bailey finds the panties on the bulletin board and loses it, demanding to know who they belong to. Callie sees Meredith's embarrassment and takes the blame, which in turn causes George to become jealous, fearing Callie might have cheated on him. A surgical patient lives what may be her last day to the fullest. Meredith must choose between Derek and Finn, and struggles coming to a decision. In the end she tells them both that she would like to try dating them both instead.
