|Debut Episode/Fic||"Mr. Hankey, the Christmas Poo"|
Mr. Mackey is the School Counselor of South Park Elementary in South Park. His most distinctive trait is his verbal tick which causes him to almost always insert the word "m'kay" into his sentences (usually at the end or after a clause).
Please visit his article on the South Park Archives for more information.
Mr. Mackey wears a green shirt, blue tie, blue jeans, blue shoes, and large, black-rimmed glasses. His hair is black and thinning, is he is well known for his exaggeratedly large Balloon head. It has been implied that his head's size is caused by the tightness of his tie.
Mr. Mackey is one of the few relatively sensible and level-headed adults in South Park. He has occasionally taught classes at the school, and taught sex education with Ms. Choksondik. After her death, he took over the fourth grade class until Mr. Garrison returned. He has a tendency to hoard, a result of being molested by Woodsy Owl as a child.
