Wouldn't the third row be "T. Rex Tireks' Tirek T. Rex" instead of "T. Rex Tireks' T. Rex Tirek?" I'm going by the flimsy logic here that a T. Rex with a Tirek head goes by "Tirek T. Rex" as opposed to "T. Rex Tirek," which the Tireks with the T. Rex heads go by, but I guess that's like calling a reverse centaur a "taurcen" or something.
