Jeff Dunham is an American ventriloquist, producer, and stand-up comedian. His style has been described as "a dressed-down, more digestible version of Don Rickles with multiple personality disorder". Describing his characters, Time magazine said, "All of them are politically incorrect, gratuitously insulting and ill tempered." Dunham has been credited with reviving ventriloquism, and doing more to promote the art form than anyone since Edgar Bergen. J.P. Williams, the producer of the Blue Collar Comedy Tour, has opined that Dunham's act is not funny on its own merits, and that his material gets a greater reaction because of the puppet characters than it would otherwise garner by itself.
