Authorities say a man sneaked into the grizzly bear exhibit at the San Francisco Zoo.
And yes, the bears were home.
Lucky for the man, a zoo patron alerted staff, and they responded immediately.
Staffers fired a warning shot to keep the bears away from the man, before securing them inside their dens.
A zoo official said that the man was conscious but unresponsive when he was rescued, and that he didn't show any apparent signs of injury.
He was taken to San Francisco General Hospital for evaluation.
The man was not identified, but officals say that he was arrested.
The zoo made headlines back in 2007 when a Siberian tiger scaled a wall and killed a 17-year-old man.
Following the incident, the zoo overhauled its safety procedures.
It is not clear how the man got inside the enclosure, or what prompted him.
