Cardiovascular and Lymphatic, Yes, the Nervous System, Too!

Scrubs was a great show. One time, that had an episode called My Musical. A patient had an aneurysm that was causing her to hear everything in song, and so the episode was, of course, a musical. They had professional (Broadway?) musicians and composers, all the songs were based on actual Broadway showtunes, and the patient, Ms. Miller, was played by Stephanie D'Abruzzo, a double-role member of the cast of Avenue Q.
Now, of all the numbers in the episode, I'd have to say that my favourite is "Everything Comes Down to Poo."
