Mother Teresa is a student at Clone High High School. She was first mentioned by Abe in the episode "Film Fest: Tears of a Clone", but didn't physically appear in an episode until "A.D.D.: The Last D is for Disorder". She is a clone of Anjezë Gonxhe Bojaxhiu (more commonly known as the original "Mother Teresa").
In "Film Fest: Tears of a Clone", Abe listed off all the students at Clone High High School, who were making independent films. He mentioned that Mother Teresa made a "teen slasher blood fest sex romp".
- Her existence as a clone defies history, since Mother Teresa died in 1997 and all of the clones were created in the 1980s. The only way her clone would be possible is if her clonemother was dug up and genetically copied, while she was still alive.
