The telephone number of W.B. Jones Heating and Air, one of the "Five Families" mentioned by Kevin, is (800) 984-3672. If you had called the number, you would get a prerecorded message encouraging you to keep your thermostat set at 67 degrees in the wintertime and 76 degrees in the summer to stay comfortable and decrease your carbon footprint. The message concluded with an invitation to wait for the next available customer service representative, but disconnected after about 30 seconds of elevator music. The number no longer works.
Although B.J. Novak wrote the majority of the episode, Jennifer Celotta and Paul Lieberstein were actually the ones who came up with the graveyard scene in the end.
In the scene with the "Five Families," one of the actors, Paul Faust, was the only first-time actor. Faust is the cousin of writer Paul Lieberstein, and had been on a tour of the set and talked to many of the writers. He made a good impression and so the character of "Cool Guy Paul" was based on him. The day before they were scheduled to shoot, the show still had not cast anyone for the role, so they called Paul in New York City and had him read the lines into a camera and e-mail to them. In less than an hour, Faust had landed the part and was flown out to Los Angeles.
At the end of the Five Families meeting, Paul Faust remarks, "Could have been handled over an email." He auditioned with an email.
