On the cult favorite show Community, main character Shirley’s catchphrase was “that’s nice,” but the way the actress was treated by a new book is anything but.

In a recent Twitter post, the actress chastised the authors of the book 1001 TV Series You Must Watch Before You Die for omitting her in the cast list under Community‘s entry. Brown is the only one of the eight series regulars not listed. That honor went instead to Rob Corddry, who played a secondary character, and only appeared in 3 episodes of the show’s 110. (Brown was in 99.) Brown further explained that she was the fourth name on the call sheet, making the omission even more egregious.

Along with leaving Brown off of the cast list, Brown also noted that Jim Rash and Ken Jeong, who played recurring characters and who also appeared in the vast majority of the show’s episodes, also deserved to be included in the book. If the show’s entry was indeed written by fans of the series, they should have known to include Brown and not Corddry as part of the main cast.

1001 TV Series You Must Watch Before You Die, a reference book with multiple authors, was edited by Paul Condon with a foreword by Doctor Who‘s Steven Moffat and an introduction by Robb Pearlman. It was published by the British publishing company Quintessence Editions Ltd., which is known for publishing reference books in a “1001…Before You Die” format.

Friends and fans posted in support of Brown, surprised and appalled that the character of Shirley was mentioned in the text but not the actress that portrayed her.

Community ran from 2009-2015, beginning on NBC and ending on Yahoo! Screen. The series, which followed a group of unlikely friends attending the wild and weird Greendale Community College, was created by Dan Harmon (Rick & Morty). The series is known for its meta-humor and creative pokes at pop culture staples, often paying homage to films and genres and parodying familiar TV tropes like bottle episodes.

The series starred an ensemble cast, the main series regulars making up the so-called Greendale Seven—Joel McHale, Gillian Jacobs, Danny Pudi, Brown, Alison Brie, and Donald Glover and Chevy Chase. Glover and Chase both left the show in season five (out of six). Jeong and Rash were also prominent faces on the show, bouncing between series regular, recurring, and guest actors throughout the seasons.

While the show was never hugely popular in the ratings, it was a darling with critics (even the ones who fumble the cast list) and a cult favorite among fans, who still wait for a cast reunion movie, as called for in the show’s rallying #SixSeasonsAndAMovie hashtag, which helped the show get picked up by Yahoo! after being cancelled by NBC, one season short of the sixth.
