Allister Monkarsh is a fellow ventriloquist critic to Graham Kensington. When Cleveland and Rallo's act goes big time, Graham invites Allister to come see them perform, unaware that due to Cleveland taking all of the credit for the act, Rallo is refusing to perform, leaving Cleveland to try to actually act. Walt spots him sitting behind him and Julius and says he hopes to intern for him some day. Cleveland tries to fake the act as the crowd gets ugly and finally apologizes to Rallo who accepts the apology and saves the act. But when Rallo takes a bow, their fake is exposed and they are banned from ventriloquism.
Allister is voiced by Stephen Root.
