A black jaguar tried to take a bite out of David Letterman!
It happened when wildlife expert Jack Hanna brought his menagerie of wild animals to the Late Show. The rare South American black jaguar looked too adorable not to pet, but watch out for those teeth. The jaguar snapped his mouth around to Letterman's hand.
Hanna chastised Letterman for petting without permission, saying, "Dave, usually you ask me if you pet them. You never asked me that question."
