They are loud, obnoxious, greedy, ignorant of other cultures asides from their own, and are inconsiderate to the safety of the environment, or even the consequences of their actions for that matter. The two are also gluttonous, and they love to eat large portions of food (preferrably Western food, even from Texas), especially if smothered with barbeque sauce. The wealthy Texan couple also use large quantities of oil, as evidenced in the Giganto SUV's and their giant oil tanker from the episode "Monster Truck Island".
