In this episode, New Zealanders Jemaine Clement and Bret McKenzie of the band Flight of the Conchords have moved to New York City to try to make it in the United States.

As Jemaine's attentions focus on Sally, a lonely Bret is forced to deal with the advances of Mel (Kristen Schaal), the band's obsessed—and only—fan.

Murray criticizes Jemaine for dating his bandmate's ex, and discusses the need to increase the group's fan base, which currently consists of only one person: the obsessive Mel (Kristen Schaal).

"Sally" was written by series co-creators James Bobin, Jemaine Clement, and Bret McKenzie, the latter two starring as the titular Flight of the Conchords.

This was inspired by an incident that happened to the band during the filming of their documentary A Texan Odyssey which covered their trip to the 2006 South by Southwest (SXSW) festival in Austin, Texas.

[4] Judah Friedlander has a cameo appearance in this episode, playing the role of the man who tries to sell Dave a cake.

[1][7][6] All three of the songs were released on The Distant Future EP in 2007, however, "The Most Beautiful Girl (In the Room)" and "Robots" appeared in live form.

[11] Murray is wearing a New Zealand All Blacks rugby shirt when the band is in Dave's pawn shop obtaining a camera.

TV, Movielink, Comcast.net and Roadrunner.com, allowed a promotional version of the episode to be streamed as part of an online marketing campaign to build up word-of-mouth for the series.

[15] On television, "Sally" debuted on the HBO in the United States at 10:30 PM on Sunday, June 17, 2007, in the time slot preceded by Entourage, and vacated by the last episode of the final season of The Sopranos.

IGN, in an advanced review of the episode, awarded "Sally" an "amazing" 9.2 out of 10 rating and called the series "The funniest show you haven't seen yet.

"[19] Blogcritics reviewer Daniel J. Stasiewski noted that the series was different for HBO, writing, "Flight of the Conchords isn’t Entourage or Sex in the City or even Extras.

"[20] Stasiewski, however, did note that the availability of the band's music on video sites like YouTube meant that watching the series was not worth the cost of a cable subscription.

[20] Further more, Stasiweski noted that while "the fun, quirky music videos that pop-up can make this long half-hour worth watching [...] the 10 or so minutes in between numbers aren’t groundbreaking comedy.
