user: Please give an overview of the show "Scrubs" highlighting unique characteristics of the sitcom.

assistant: <think>
Scrubs focuses on the unique point of view of its main character and narrator, Dr. John Michael "J.D." Dorian (Zach Braff) for the first eight seasons, with season nine being narrated by the new main character Lucy Bennett (Kerry Bishé). Most episodes feature multiple story lines thematically linked by voice-overs done by Braff, as well as the comical daydreams of J.D. According to Bill Lawrence, "What we decided was, rather than have it be a monotone narration, if it's going to be Zach's voice, we're going to do everything through J.D.'s eyes. It opened up a visual medium that those of us as comedy writers were not used to." Actors were given the chance to improvise their lines on set with encouragement by series creator Bill Lawrence, with Neil Flynn and Zach Braff being the main improvisors.

Almost every episode title for the first eight seasons begins with the word "My". Bill Lawrence says this is because each episode is Dr. John Dorian writing in his diary (revealed in the commentary on the DVD of the first-season episode "My Hero"). A few episodes are told from another character's perspective and have episode titles such as "His Story" or "Her Story". Apart from a brief period of narration from J.D. at the beginning and the end, these episodes primarily contain internal narration from other characters besides J.D. The transfer of the narration duties usually occurs at a moment of physical contact between two characters. Starting with season nine, the episode titles start with "Our..." as the focus has shifted from the perspective of J.D. to a new group of medical students. The webisodes that accompanied season eight, Scrubs: Interns, also were named "Our...".</think>
The television show Scrubs aired from 2001 to 2010 and was filmed primarily through the point of view of the main character, John Michael "J.D." Dorian. These episodes were all titled with the format of "My..." to further highlight J.D.'s point of view. Episodes not filmed through J.D.'s point of view were titled with "His...," "Her...," or "Their..." to allow other characters to narrate and tell a story through their point of view.

user: What are teeth?

assistant: Teeth are a part of your digestive system.  They are used to mash and grind food to allow your digestive system to be able to process it into nutrients and energy for the body.  Most humans have 32 teeth, and enamel is the protective outer layer of the teeth.  Teeth attach the the mandible bone and are very strong.  If you eat a lot of sugar the enamel on the teeth will break down causing cavities that have to be fixed and repaired at the dentist.

user: Im considering buying a boat?  How do I decide which boat meets my needs?

assistant: Things you should consider when making a boat buying decision.  How much space do you have to store the boat?  Will the boat be used in fresh or salt water?  Inboard motors are great for fresh water environments.  Outboard motors are often preferable for salt water applications. If you plan on using the boat for fishing, you need to decide if you will be fishing offshore or inshore.  Inshore fishing requires a smaller draft.  Draft is how much water a boat needs to float.  Offshore fishing boats have deeper drafts based on the hull.  Offshore boats can handle rougher water based on more aggressive hulls.  Offshore boats have steeper dead rise.  Dead rise is the angle of entry for the boat hull.  More aggressive dead-rise leas to a softer land in harsh water conditions.
