A Leopard Steals an Antelope Leg from a Sleeping Crocodile's Mouth

This happened at Luangwa National Park in Africa. Someone filmed a leopard stealing antelope meat from a sleeping crocodile's mouth. It starts with the leopard taking a small chunk from the croc's mouth. And then it decides to come back for more. This time it snatches a whole leg. That part is really interesting because you can see the crocodile open its eyes, but it doesn't attack, or even move.
