That one's been a favorite since I first saw it. I like the idea that the lion slowly munches the whip as though it were a string of licorice until gulp, the last big joins the tamer in his stomach.

Another neat one is the Jeep ad that implies that a bear has eaten a bunch of people who wanted to explore there wilderness. I'd append a link but my phone is a potato - doing a Google image search for "Jeep bear advertisement" out to let you find it.
