Many balloon twisters will tell you the answer is anywhere they want, but I put a little thought into this question and have come up with the true answer. An 800-pound gorilla can only twist balloons where the zoo keeper allows it to go. The zoo keeper is controlled by the zoo management and the trustees. Their actions are founded on what the public dictates, so the answer is to the question is… you the public, tells an 800-pound gorilla where to twist.
I would like to thank all the people who have hired me to twist balloons at their parties these past 24 years and for allowing me the opportunity to entertain your family and friends.
Why do you assume that the Gorilla is in a zoo, rather than in the wild where they belong?
Since gorillas are not native to the USA and I have only seen them at the San Diego and Brook Field zoo it seems the most logical place to have them. Beside an 800 lb gorilla is too big for a house pet. I did know a guy who had a 5’ alligator (Bubba). I did a cable TV interview with him and I was very careful when I touched him. Bubba roamed the room and had no restraints.
