The “Hairy Houdini”: The Orangutan Who Kept Escaping the Zoo—Then Threw Rocks at Another Orangutan
For years, one orangutan at the San Diego Zoo became famous for something remarkably unusual: he repeatedly figured out ways to escape his enclosure and wander around the zoo.

His name was Ken Allen, a Bornean orangutan born at the San Diego Zoo in 1971. He eventually became known as the “Hairy Houdini” because of his extraordinary ability to outsmart the zoo’s security measures. (SDZWA Timeline)
And one particularly strange part of his story involved another orangutan named Otis—and a few flying rocks.

Ken Allen Was a Master Escape Artist
Ken Allen became notorious in the 1980s after repeatedly escaping from his enclosure.
In 1985, he escaped twice within roughly six weeks. According to a contemporary Los Angeles Times report, Ken managed to scale the enclosure wall and mingle with zoo visitors before being caught and returned to his exhibit. (Los Angeles Times)
The zoo was so puzzled by his escapes that keepers eventually resorted to an unusual strategy: they disguised themselves as ordinary tourists so Ken would not realize he was being watched.
One keeper even observed Ken attempting to climb out of the enclosure while dressed like a regular zoo visitor. (Los Angeles Times)
The San Diego Zoo later described Ken as exceptionally intelligent, creative and skilled at solving problems. The zoo's historical archive notes that staff members even went undercover as tourists to figure out how he was escaping. (SDZWA Timeline)
He Didn't Seem Interested in Going Far
Interestingly, Ken's escapes were not necessarily attempts to flee the zoo permanently.
The San Diego Zoo's historical account says that after getting out, Ken would often simply hang around the zoo until keepers came to take him back, apparently quite willing to return to his enclosure. (SDZWA Timeline)
A 1987 Los Angeles Times report documented another escape in which Ken spent about 15 minutes wandering around the park. On that occasion, however, he traveled farther than usual and had to be chased back toward his enclosure. (Los Angeles Times)
Zoo officials emphasized that an escaped orangutan could still be dangerous because of its tremendous strength, even if the animal was not intentionally aggressive toward people. (Los Angeles Times)
Then There Was Otis
One of the most memorable details in Ken Allen's escape history involved another orangutan named Otis.
A 1985 Los Angeles Times report stated that during one of Ken's escapes, he reached the area of a neighboring orangutan and threw rocks at him. (Los Angeles Times)
That detail is the basis for the viral claim that Ken would stop by Otis' enclosure during his adventures.
However, there is an important distinction between what is documented and what has been added to the story over the years.
Did Ken “hate” Otis?
That part is not something we can establish as fact.
The contemporary report documents Ken throwing rocks at a neighboring orangutan, but describing Otis as an orangutan Ken “hated” is an interpretation rather than something that can be proven from the available historical records.
So while the rock-throwing incident is documented, the emotional explanation attached to it in viral posts should be treated cautiously. (Los Angeles Times)
The Zoo Had to Think Like Ken
Ken's intelligence made him particularly difficult to contain.
Zoo staff inspected his enclosure, increased security measures and even brought in rock climbers to examine the walls for possible escape routes.
But Ken repeatedly demonstrated that he could discover solutions that humans had overlooked. The San Diego Zoo's historical archive describes him as an animal who seemed to enjoy the challenge of finding new ways around obstacles. (SDZWA Timeline)
His reputation eventually became so large that he had his own fan club, merchandise and even a song written about him.
The nickname “Hairy Houdini” stuck.
His Escapes Became Part of Zoo History
Ken continued to make headlines for years.
In 1987, for example, he escaped again after a problem with the moat surrounding his enclosure. He wandered through the zoo before staff eventually returned him safely. (Los Angeles Times)
His escape skills even appeared to influence other orangutans. A later Los Angeles Times report described two of Ken's female companions escaping from their enclosure after taking advantage of a misplaced cleaning tool. (Los Angeles Times)
Ken eventually became one of the most famous animals in the history of the San Diego Zoo.
He died in 2000 at age 29 after developing lymphoma. The Los Angeles Times reported that he had become so beloved that he had his own dedicated fan club, known as the Orang Gang. (Los Angeles Times)
The Truth Behind the Viral Story
The viral image's basic story has a real historical foundation, but some of its wording is exaggerated.
What is confirmed:
Ken Allen was a real Bornean orangutan.
He lived at the San Diego Zoo.
He repeatedly escaped from his enclosure.
He wandered around the zoo during some of his escapes.
Zoo staff used disguised “tourists” to observe him.
A contemporary report documented him throwing rocks at a neighboring orangutan, identified in later retellings as Otis. (Los Angeles Times)
What should be treated as interpretation:
That Ken “hated” Otis.
That throwing rocks at Otis was his “only act of violence.”
That every escape was simply a peaceful stroll around the zoo.
The historical record is more nuanced than the viral caption.
VERDICT: 🟢 LEGITIMATE STORY
The story is based on a real historical animal and documented events.
Ken Allen really was an extraordinarily clever escape artist, and contemporary reporting confirms that he escaped repeatedly and at one point threw rocks at a neighboring orangutan. However, the viral caption adds emotional language such as “an orangutan he hated,” which cannot be verified as Ken's actual motivation.
In other words, the “Hairy Houdini” really existed—and the rock-throwing incident really happened. The dramatic interpretation is where the viral version goes beyond the evidence. (Los Angeles Times)
