Don't be a dork. Gorillas are dangerous animals.

Sure, they probably shouldn't be kept in zoos at all, but put yourself in that spot, watching a 440-pound Gorilla tossing around a human child, and make the choice. 

A 440 pound Gorilla is probably several times stronger than a 440-pound man would be, which probably presents a clear and present danger to any human being. Duh.

Still, there are a lot more bratty-assed children than Gorillas in this world... Just saying.
