Marx contributed to a musical episode of the NBC sitcom "Scrubs", an episode that the "New York Times" reported "energized a cast and crew that, at a point when most situation comedies are sputtering along or dead, have recently been doing some of their best work." In comparing it to his work on "Avenue Q", Marx said: "It took us five years to write "Avenue Q" ... There were a million readings and previews and staged readings. With this thing, we wrote the songs in a week. They rehearsed for a week. They filmed it in a week, and it was done. It was liberating, and a collaborative effort that created a much more feel-good way of working."
