The man whose standup concerts rule the comedy world, Jeff Dunham, is coming to the Constant Center as part of a full slate of shows that offers his millions of fans brand new laughs and hilarious additions to his famed troupe of sidekicks. In the coming months, concertgoers will meet two new Dunham characters: Achmed Junior, the not-as-equally skeletal son of Achmed the Dead Terrorist, and Little Jeff, a mini-version of the ringmaster himself.
