Texas is one of the students in Stan's CIA training class in "The Never-Ending Stories". When he finds out they will listen to anything he says, he regales them with his boring stories and then quizzes them about it. Texas revealed that Stan's most exciting thing of the week was watching Addams Family Values from start to finish.
Thanks to Stan's neglect to actually teach anything useful and avoid the wrath of the dean, he cheats his students though the class finals where they do so well they are fast-tracked into what would be considered a suicide mission. As they flee for their lives from guerrillas, Texas tries to convince them to jump a gorge due to Stan's cheating influence, and leads the way by jumping and falling with a smash.
