One episode called for Dr. and Mrs. Craig to visit Philadelphia. Inspired by returning to Independence Square, William Daniels sang a few lines of the song, "Sit Down, John!", from 1776 (1972). (The line was "It's hot as hell in Philadelphia!") The moment was included in the episode. (He also mentioned that there was something about being in the city of Philadelphia that just made him want to sing and dance). Daniels played John Adams in that movie. In this episode Dr. Craig (Daniels) also mentions to his wife that back in medical school he was "obnoxious and disliked" which is also something said by John Adams to his wife in "1776".
Dr. Mark Craig:
"Premature is a relative term, Donald."
Throughout the series, Dr. Daniel Auschlander suffers from late-stage Liver Cancer and yet he is seen repeatedly as drinking "very good" Scotch after hours with his staff in his office. Alcohol consumption only aggravates Liver Cancer and hastens death.
After the credits, they show the MTM kitten wearing a surgical mask and smock to match the show. In final episode, the MTM kitten is shown underneath the credits, hooked up to life-support. At the end of the credits, the kitten flatlines.
The versions shown on Bravo cable network in the United States have many of the songs used throughout the series replaced with generic stock music, probably due to licensing issues.
