A drunk man claimed to be Tarzan and tried to swing into a monkey exhibit at his local zoo.
John William Rodenborn first attempted to break into the bird exhibition at Santa Ana Zoo in California but failed and swiftly moved onto the monkey enclosure.
Zoo director Kent Yamaguchi was forced to telephone police to get Rodenborn removed and a transcript of the conversation has been made public.
He said: "We have a gentleman who is - appears to be - under the influence of something and is climbing in our trees and jumping into animal exhibits."
Officers removed the intruder, who was in possession of methamphetamine and claimed to be the feral child who becomes Lord of the Jungle.
Thankfully none of the animals were harmed during the incident.
