LOL! That's the first reasonable explanation I've ever heard for Carville's existence.
I SWEAR that's what happened. Watch a movie with him, have him stand upright in your head, put on a suit, some makeup to cover the pastiness, and some caps and crowns, and viola. James "Smeagol" Carville. :) Mary Matlin has the strongest constitution of any woman on Earth, because she sees him at home when the makeup and suit come off, stromping on all fours, grabbing fish from the tank for a quicke snack, and his other less than appealing habbits. :)
