There are two organizations which share the acronym "NAMBLA" on South Park; the "North American Man-Boy Love Association" and the "North American Marlon Brando Look-Alikes". Both of these groups appeared in the Season Four episode, "Cartman Joins NAMBLA".
North American Man-Boy Love Association
The North American Man-Boy Love Association is an organization that promotes sex between grown men and young boys and is working to abolish age of consent laws, and the group exists in real life as well. Cartman, in an effort to separate himself from his friends and seek out adult companionship, agrees, unknowingly, to become poster boy for the organization, whilst he is in fact being eyed by a number of pedophiles. The NAMBLA members throw a party and invite the other young boys in town, including Butters, Craig, Clyde and Timmy. The children are chased around by the men attempting to rape them but manage to escape and Stuart McCormick accidentally walks into the room where the men are and he is confused for one of the boys, and he is raped by the men. They are arrested by the police at the end of the episode.
- Pedophilia - These men tried to have sex with male children.
- Rape/Attempted Rape - They tried to rape boy children and raped Stuart McCormick
North American Marlon Brando Look-Alikes
This is the other organization which shares the acronym "NAMBLA" only for this group it stands for the "North American Marlon Brando Look-Alikes" and does not exist in real life. Their spokesperson is Dr. Alphonse Mephesto. They have a continual row with the other NAMBLA about the ownership of "nambla.com". It was this NAMBLA Dr. Mephesto suggested Cartman join, presumably because he looks like a young Marlon Brando. They are often mistaken to be "the other NAMBLA" by the FBI. The North American Man-Boy Love Association is disliked by the North American Marlon Brando Look-Alikes because of the North American Man-Boy Love Association's pedophilia.
