Carlo is the capo that replaced Vito in construction. He has apparantly brought in about one third of what Vito did. He is seen in the backseat of a car Tony is riding in while Tony scolds him about not earning enough: "Maybe you should go suck a c*** instead of watchin TV Land or whatever the f*** else you do. Cuz when Vito was in charge of construction, he brought in 3 times as much as you."
One of the funniest lines of the show.
