Security camera footage at the Ramat Gan Safari in Tel Aviv shows the horned trio happily trotting through an open gate, bravely venturing into the wide world beyond. A guard can be seen briefly giving chase before realizing, perhaps, that he was helpless to halt their eager exodus.
According to the Jerusalem Post, the rhinos couldn't have planned their escape any better. Officials say that the guard on duty at the time had fallen asleep, allowing the animals to take advantage of the fact that two gates meant to hold them in had been left wide-open. (Ramat Gan considers itself a safari-style zoo - animals are allowed to roam freely in large groups on the 250-acre grounds.)
