It guest stars Stephen Colbert as Andy's college friend Broccoli Rob and Ben Silverman as an investor.
The series depicts the everyday lives of office employees in the Scranton, Pennsylvania branch of the fictional Dunder Mifflin Paper Company.
In the episode, Andy Bernard (Ed Helms) invites his old college a cappella group, Here Comes Treble, to perform for the office during Halloween.
Meanwhile, Dwight Schrute (Rainn Wilson), with the help of Nellie Bertram (Catherine Tate) tries to track down a person who is using prescription anxiety pills.
"Here Comes Treble" was viewed by 4 million viewers and received a 1.9/5 percent rating among adults between the ages of 18 and 49, ranking third in its timeslot.
Nellie Bertram admits that the pill belongs to her; she explains that she doesn't want Dwight to find out, as she once saw him yell at Phyllis Vance for "sneezing incorrectly."
"Here Comes Treble" was written by supervising producer Owen Ellickson, marking his third writing credit for the series, after the eighth season episodes "Pool Party" and "Fundraiser".
[7] Former NBC Entertainment co-chairman Ben Silverman also guest stars as one of the investors who attends Jim's meeting.
Kevin Malone (Brian Baumgartner) is dressed as Charlie Brown, the protagonist in the comic strip Peanuts by Charles M.
The group sings the Rose Royce 1976 single "Car Wash", the 1983 Culture Club song "Karma Chameleon", and Edwin McCain's 1998 hit "I'll Be".
[10] During their Skype-argument Broccoli Rob mentions that he collaborated with Trey Anastasio, the frontman for the jam band Phish.
This made "Here Comes Treble", at the time of its airing, the lowest-rated episode of The Office, beating the eighth season entry "Fundraiser", which was viewed by 4.17 million viewers.
[16] The Office finished third in its time slot, being beaten by an episode of the American Broadcasting Company (ABC) series Grey's Anatomy which received a 3.0/8 percent rating and an entry of the CBS drama Person of Interest, which received a 2.9/8 percent rating[15] Despite this, The Office was the highest-rated NBC television program of the night.
He criticized the characterization of Andy and said that the character had "hit a plateau when his fist went through that wall in season three" and represented "a grinning puppet who can be imbued with some of Michael Scott's leftover tics and remind people he went to Cornell".
[19] Michael Tedder of New York felt that the main story was weak and that the "plot line might have made more sense last year, with Andy trying to take his mind off troubles with Erin or Robert California by trying to regress to his college days without it working, but these days Andy is the boss and has the girl."
She wrote that, "Each thread provided some interesting character development or set up future storylines, but, crammed together in the same 21 minutes, they made for a slightly disjointed-feeling episode.
Adams compared Colbert's cameo to former lead actor Steve Carell's appearance in the first series of the BBC Two sitcom Life's Too Short, calling it "an unfortunate echo".
[8] White wrote that his cameo was not "quite the sublime experience I was hoping for" largely due to the amount of anticipation that was put into his appearance.
