he second season of the American comedy-drama television series Scrubs premiered on NBC on September 26, 2002 and concluded on April 17, 2003 and consists of 22 episodes. For the second season Neil Flynn was made a series regular. Colin Hay guest starred for the first time. It is also the first time an episode gives the narration to another regular, in "His Story."
The show used a longer opening credits sequence for episodes 1 and 2, moving through the ward rather than just two beds, including a shot of Flynn as The Janitor, showing the names of the series regulars and ending with the chest X-ray showing the heart on the left side of the chest. NBC wanted longer content in the episodes so the credits permanently returned to the shorter version in episode 3, without Flynn nor actors names and with the mirror image chest X-ray.Overview from themoviedb.org
