"You see all these lions on TV, in movies, in commercials or whatever, and they're often tame and kind of sweet. Or you see them lying around with their paws in the air, sleeping in the shade on the savanna. But you need to realize something. The reason lions have lots of time to sleep is that they are very, very effective killers. They don't need to expend a lot of energy, because as long as there is prey, they'll eat just fine."
