Mr. Morris is the former janitor for Lakewood Elementary School. In "April 9th", the school was damaged by a fire and Mr. Morris broke his leg. Because of his leg, he retired and moved to Roswell, New Mexico, onto his daughter's ranch. Though he moved in Season 7, he made a couple of non-speaking appearances in episodes like "Francine's Pilfered Paper." In the Postcards from Buster episode "Alien Adventure," he appears when Buster visits Roswell, New Mexico. He appears in a flashback in the Postcards from Buster episode "Coming Together." The flashback reused a part of "April 9th," when Buster goes to visit him in the hospital.
In "Strangers on a Train," Mr. Morris is seen in a green uniform, appearing to be working as a janitor for the train station, implying that he worked there at some point.
It is said that he used to be a dog groomer, he can speak Portuguese, and he even had an accordian by the name of Beatrice.
- Buster: Mr. Morris is very good friends with Buster. They have many things in common, including that they both believe that aliens exist and they both have asthma.
