The show is hosted by Jeff Ross who also serves as one of the judges on each show. Comedian and show co-creator Brian Moses announces each competitor and also serves as referee. The winners of each battle are determined by a panel of guest judges that include two or more comedians or other celebrities. In addition, there were comedians added to the final sixteen competitors list who did not compete in the regionals. The final eight battles of the second season were filmed on the
Sunset Strip and the final battle was also broadcast live. The show changed it format in the third season and abandoned the bracket-style tournament. As a result there were no preliminary regional battles and instead each episode featured only two battles per episode over six episodes. In addition
Anthony Jeselnik and
Nikki Glaser served as judges on all six episodes and they were also joined by
Pete Davidson during the final episode. The final episode also marked the first time that Ross took to the stage as a battler during the show; he battled with
NBA player
Blake Griffin. ==International versions==
