Jeff Dunham
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 that it would otherwise not garner by itself. Blue Collar veteran Bill Engvall, a friend of Dunham's insists otherwise, saying that Dunham is inherently funny with or without the puppets.
