SUN TZU SAID THAT. And I think he knows a little bit more about fighting than YOU DO, pal! Because he invented it! And then he perfected it so that no man could best him in the ring of honor!
THEN he used his fight money to buy two of every animal on earth! And then he herded them onto a boat! And then he beat the crap out of EVERY SINGLE ONE.
And from that day forward any time a bunch of animals are together in one place it's called a ZOO!
