The x-ray with the show's title shown in the beginning is turned the wrong way: the heart should be seen on the right hand side. This was an intentional mistake put in by creator Bill Lawrence
to represent the core idea of the show: young doctors in over their heads. Bill Lawrence reminds viewers that this goof was completely intentional in interviews, DVD commentaries, and virtually any other available opportunity. See more
Well, gosh - I guess I became a doctor because ever since I was a little boy, I just wanted to help people. I don't tell this story often, but I remember when I was seven years old, one time I found a bird that had fallen out of its nest, and so I picked him up and I brought him home, and I made him a house out of an empty shoebox.
I became a doctor for the same four reasons that everybody does - chicks, money, power and chicks.
