Our city's most charming animal charmer, Jack Hanna, admitted to David Letterman last night that he once lost "two sea snakes that were venomous... They got out and they pushed the lid up and they went down the drain into the sewer system of Columbus. I never told anybody."

This, of course, was in 1986, but, as Hanna admits, "they could be real big" by now. Watch the video here. The part about snakes in our sewers starts around 2:44, but watch the whole thing to appreciate how stinking cute that leopard cub is.
