Animal ... my old man told me the same thing (he worked every summer on his uncles farm as a kid), except they had an X shaped thing they would chain the bulls head to.
As for Gorilla VS human, I would root for the human, but wouldn't bet a dime on him.
Ever seen a few gorillas fight it out on the Discovery channel? Shiiiiet. Don't wanna get in their way! I don't care how big and juiced up you are.
And they are not just strong and wild, them things are tough as nails! I remember going to the Zoo and watching them go ape-shiet when the kids antagonized them. They would go nuts and literally hurl themselves at the armored window hitting it head first, didn't even phaze them.
Naaah Humans don't stand a chance...
